New in Silverfrost FTN95 8.61 (Jun 24, 2020)

New in Silverfrost FTN95 8.50 (Jan 1, 2020)

New Features:
A new Silverfrost utility called EditSVG is provided. This can be used to form images from a number of SVG sources into one composite image.
The size of the FTN95 stack is effectively no longer limited. The default size is 32MB and this can be extended via the SLINK64 "stack_size <hex-value>" command or the new SLINK64 "stack <hex-value>" command where <hex-value> is the decimal number of decimal megabytes required.
Fortran 2003 standard I/O FLUSH statement added. (Win32/x64 only)
Fortran 2003 standard I/O routines, keyword argument IOMSG added. (Win32/x64 only)
Fortran 2003 standard intrinsic GET_ENVIRONMENT_VARIABLE added.
Fortran 2008 standard intrinsic EXECUTE_COMMAND_LINE added.
Routines READFLONG@ and WRITEFLONG@ have been added (x64 only). These are the same as READF@ and WRITEF@ respectively except that they take INTEGER*8 values for NBYTES and NBYTES_READ.

Microsoft Visual Studio 2017 plugin
ClearWin+: The buffer size for %RE was previously limited to 32K characters. This limit has now been removed but in such cases the buffer will not be automatically updated and an explicit call to GetEditText@ will be required in order to copy the text to the buffer. If this copying takes place within an associated callback function then clearwin_info@("CURRENT_CONTROL") returns the required HWND.
ClearWin+: ALLOCATE(data1,ABSOLUTE_ADDRESS=addr) can be used in a callback relating to %ud. addr will be obtained via CLEARWIN_INFO@("USER_DATA") and data1 will be an object of the same kind as that used in the call to LOC.
Outline summary of bugs that have been fixed:
A PRIVATE TYPE in a MODULE was not private.
A USE ONLY attribute for a MODULE TYPE was not working correctly.
There was an internal compiler error with /64 and PRINT a(i,1:n).

New Features:
Plato has been upgraded to a 64 bit application with integrated debugging for 64 bit applications (as well as the existing integrated debugging for 32 bit applications). Users who don't have a 64 bit operating system should now use Plato32.
A bounds check has been added for an assignment that has the form w(1:n) on the left hand side.
A number of minor FTN95 library functions (such as RANDOM@) have be added to the list of designated "FTN95 intrinsics".
/CHECK_WINIO option to specifically check WINIO@ commands
ClearWin+: Extra options for %sl to control appearance
ClearWin+: Options [external],[frame_pen=dval], [title_hfont=hval] and [function=fun] have been added to the native %pl

ClearWin+: PRINT_GRAPHICS@ provides a simple interface to print graphics such as native SIMPLEPLOT graphs.
ClearWin+: %sb has been added in order to provide an alternative to the %ob status bar
ClearWin+: The format code %rf now accepts the input of a comma. This is transcribed to a decimal point.
ClearWin+: The format code %il can now be used with the tilde (~) modifier. The result is that the limits are not applied to the displayed %rd integer value but (on error) an alert icon appears and the text colour changes to red.
ClearWin+: A new option [panel=val] has been added to %br. val is the integer value of a %sb panel
SIMDEM DLLs are now automatically scanned by the linkers. This makes using SIMDEM a smoother process.
Outline summary of bugs that have been fixed:
In 32-bit code, some floating point errors caused the exception dialog to show a garbage error message.
A certain TYPE initialisation was causing FTN95 to crash.
In 64-bit mode, the use of TRANSFER to create invalid REAL constant was causing FTN95 to crash.
In 64-bit mode, BTEST was failing for INTEGER*8 arguments.
The FTN95 option /XREF was failing in certain cases.
In 32-bit mode, if(A.LT.A) was giving an incorrect result.
A regression at 8.20 has been fixed. This related to passing an array A enclosed in brackets as in: CALL sub1((A)).
64 bit CLOCK@ and DCLOCK@ were returning CPU time rather than the required elapsed time.
A DO loop with 64 bit integer parameters was causing an internal compiler error.
SYSTEM_CLOCK was giving inaccurate results in 64-bit mode.

SDBG64 more stable when debugging multi-DLL applications
ClearWin+: draw_point@ in GDI+ mode now draws correctly

New in Silverfrost FTN95 8.10 (Oct 12, 2017)

New Features:
The FTN95 option /CHECK is now available in 64-bit mode.
The FTN95 option /OPTIMISE is now available in 64-bit mode but is still under development.
64-bit /CHECK includes a compile time check on winio@ arguments - that they have the correct type. Initially this feature is only available with /64 /CHECK.
SET_TRAP@, TRAP_EXCEPTION@, LABEL@ and JUMP@ are now available in 64-bit mode.
A new FTN95 option /BINARY_FOLDER has been added. This allows the user to specify the path for the object code (for example .obj or .dbk file). It provides an alternative to specifying the full path via /BINARY.
ClearWin+: A native form of the winio@ graph control %pl is now available. See cwplus.enh for details.
ClearWin+: Functions like COPY_TO_CLIPBOARD@ now have 64 bit equivalents COPY_TO_CLIPBOARD64@. See cwplus.enh for details.
ClearWin+: The subroutine GET_FILTERED_FILE@ and the function GET_MULTIPLE_FILENAMES@ have been updated. See cwplus.enh for details
ClearWin+: A tilde modifier can now be used with %ga in which case the list of "state controls" is replaced by a single array.
ClearWin+: A tilde modifier can now be used with %ps in which case the list of "sheet handles" is replaced by a single array.
ClearWin+: A new routine PROGRESS_BAR@ has been added that can be called before each call to DISPLAY_DIB_BLOCK@
ClearWin+: A window with a %LW control variable CTRL has CTRL initially set to -1. Setting CTRL to zero or a positive value causes the window to close when WINDOW_UPDATE@(CTRL) is called. A new alternative is to set CTRL to -2 before a call to WINDOW_UPDATE@(CTRL) and this causes the window to close after a short delay. This can be used to seamlessly modify a window by closing the window and then recreating it with similar features and the same position and size.
ClearWin+: CLEARWIN_INFO@("EXTENDED_ERROR") has been added. It provides the result of a call to the Windows API function CommDlgExtendedError().
A new function called ProcessMemoryInfo@ has been added to the library. This provides easy access to the Windows API function GetProcessMemoryInfo.
Microsoft Visual Studio 2015 plug-in.
Outline summary of bugs that have been fixed:
SDBG64 has had many issues fixed and features added
A regression that limited a 64-bit ALLOCATE statement to 2GB size blocks has been fixed
INTEGER*2 and INTEGER*1 division were failing in 64-bit mode.

The standard intrinsic GET_COMMAND_ARGUMENT was not giving a correct status in 32 bit mode and could omit the final character in 64 bit mode.
Problems calling DLLs that reside above 4GB in 64-bit mode have been fixed

New in Silverfrost FTN95 8.05 (Jun 21, 2016)

New Features:
FTN95 provides some Fortran 2003/2008 features that required the command line option /F2K. These features are now provided by default. In order to restrict the code to Fortran 95 use /-F2K.
CODE/EDOC is now available in 64-bit mode
The following Fortran 2008 standard intrinsics are now available: ERF,ERFC,ERFC_SCALED,GAMMA,LOG_GAMMA,BESSEL_J0,BESSEL_J1,BESSEL_Y0,BESSEL_Y1,BESSEL_JN,BESSEL_YN. See for example http://fortranwiki.org/fortran/show/bessel_j0.
_WIN32 and _WIN64 are prefined for use in conditional compilation CIF. For example, the CIF(_WIN64) block of code will be compiled when the options /64 /fpp are applied on the FTN95 command line. This is particularly useful for CODE/EDOC blocks that require conditional compilation when implemented for both 32 and 64 bit code. In other contexts, an equivalent run-time condition is "IF(KIND(1_7) == 4)THEN".
The following undocumented Win32 routines have now been ported to 64 bits: FPOSLONG@, RFPOSLONG@ and FPOS_EOFLONG@. These are similar to FPOS@, RFPOS@ and FPOS_EOF@ but take INTEGER*8 position arguments. Note that other arguments are still INTEGER*2.
ClearWin+ can now be used to generate SVG files by calling OPEN_SVG@ before drawing the graphics (this is analogous to generating printer output). SVG is a vector graphics format.
Outline summary of bugs that have been fixed:
Compile time array bounds check failure has been elevated from WARNING to ERROR when using /CHECK or /BOUNDS_CHECK
The SUM intrinsic with a scalar MASK was giving incorrect results
The UBOUND intrinsic, when used as an array index was being treated as a vector subscript
A substring of an element of a character array was causing a backend failure. (64-bit only)
A regression caused the compiler to crash when raising a complex value to the power 0.5. This has been fixed
GET_DIB_SIZE@ when used with USE_GDIPLUS_IMAGE_FILES@ was giving a SUCCESS report when attempting to access a non-existent file.
Error number 612 was being appied out of context
INTENT(OUT) arguments with TYPE initialisation were causing runtime failures when OPTIONAL and not present
The WHERE construct was sometimes failing when the body contained an assignment to a temporary array
A GO TO statement within an IF construct was giving incorrect results with /OPT

NAMELIST was failing when used in an internal (CONTAINS) subprogram
In a certain context a USEd MODULE user TYPE was falsely reported as not being defined
A stack leak was causing WRITE statements involving multiple calls to TRIM to fail with /FULL_UNDEF
Personal Edition did not allow /64 compile time switch
ClearWin+: �[Shift+Tab] was not responding as expected.
ClearWin+: A standard callback SETF has been added. This is equivalent to the standard callback SET but takes double precision values
ClearWin+: The property sheet control %ps was not working correctly when [hot_track] or [ms_style] was used together with a callback function
ClearWin+: %ss and browse_for_folder@ were not working for 64-bit applications.
New Features:
FTN95 can now generate 64 bit executables and DLLs. For details see the 64 bit release notes.
The display resulting from the FTN95 command line option /CONFIG has been simplified and now only edits the global FTN95 configuration file. Use a new option /CFG to edit the local FTN95 configuration file
ClearWin+: A new function called GlobalMemoryStatus@ has been added to the library. This provides easy access to the Windows API function GlobalMemoryStatusEx.
ClearWin+ now makes use of the "DPI awareness" features first available with Windows 8.1. This means that, where possible, ClearWin+ will take advantage of the Windows API features designed to handle high DPI display settings which otherwise can lead to clipped text and blurry images.

New in Silverfrost FTN95 8.00 (Jun 21, 2016)

New in Silverfrost FTN95 7.20 (Jan 13, 2016)

New Features:
A new KIND value has been introduced for integers. INTEGER(KIND=7) has the size of an address which depends on the type of the executable (32 bit or 64 bit). The same kind value is to be used when /ALT_KINDS is applied
ClearWin+: GET_DIB_SIZE@, GET_DIB_BLOCK@ and IMPORT_IMAGE@ have been extended in order to provide access to a wider range of image files via the Microsoft GDI+ library.
ClearWin+: A tilde modifier (~) can now be used with %wp with the result that plain text placed on top of the wallpaper will be transparent. In other words the text will have the wallpaper as background.
ClearWin+: The previously undocumented function browse_for_folder1@ can be used to open a dialog box with the option to create a new folder.
Outline summary of bugs that have been fixed:

Empty character format and list directed write statement output a line with a single space rather than an empty line.
The REC specifier was allowed for READ and WRITE statements on a unit opened for sequential access.
Writes starting with '1' on units opened with FORM='PRINTER' didn't output a form feed.
A certain PARAMETER initialisation was failing with /ALT_KINDS.
A star-sized array argument in an internal function was giving a false run-time bounds check error.
The SHAPE intrinsic is now available within a PARAMETER initialisation.
Arrays declared with the PARAMETER attribute where not protected from run-time changes.
ClearWin+: �[Shift+Ins] was over-riding the typing of an underscore character in an edit box. This has been fixed.
ClearWin+: %dr (dropped files) has been tidied up so that the clearwin_string@ data is correctly reset and a crash is avoided.
ClearWin+: Various reported problems when using UTF8 characters have been resolved.
ClearWin+: Previously undocumented functions set_integer_limits@ and set_float_limits@ have been improved. These routines correspond to %il and %fl respectively and allow changes to be made at run time.

The /ISO command line option previously did not generate an error report when a TYPE or PARAMETER within an INTERFACE was inherited from the host.
Using /UNDEF with certain CHARACTER variable members of a user TYPE was causing an access violation.
The intrinsic function ISHFT was producing incorrect results for INTEGER*2 arguments.
Some duplicated double precision value arguments where not being passed correctly.

New in Silverfrost FTN95 7.00 (Nov 21, 2013)

New Features:
ClearWin+ is now available in the form of a 64 bit DLL called clearwin64.dll for use with third party 64 bit compilers. Routines in this library that previously ended with the @ symbol now end with $. In order to allow parallel development, FTN95 has been extended so that routines such as winio@ can now end in $ as an alternative to @. Also new standard modules are provided so that all ClearWin+ library routines for FTN95 can take this alternative form. For further information, search for "64 bit" in ftn95.chm.
ClearWin+ now accepts UTF-8 encoded character strings.
EXPORT_IMAGE@ and IMPORT_IMAGE@ now accept .PNG files and resources.
Four new library routines (START_THREAD@, WAIT_FOR_THREAD@, LOCK@ and UNLOCK@) have been added in order to initiate and manage Win32 threads.
The default ClearWin+ colour mode has been changed from "VGA colours" to "RGB colours".
ClearWin+: A new format code %em has been introduced to allow you to put icons in the left hand column of menus.
ClearWin+: A new format code %nw has been introduced. %nw takes one argument and this is the handle (%hw) of a window that has already been created
�[Ctrl+1] etc. added to list of accelerator keys allowed
The options [colour=] and [color=] have been added to %gr.
%th[balloon] now provides a tooltip in the form of a balloon.
%rd now takes the option [radix=n] where n is an integer in the range 2 to 36.
%ob now takes the option [rounded] to provide rounded corners
clearwin_info@("TOOLTIP_HWND") now returns the HWND for Microsoft style tooltips
Visual Studio 2012 plugin
Outline summary of bugs that have been fixed:
Local use of a name that duplicates the name of an intrinsic (e.g. SUM) was confusing the compiler.
FTN95 was allowing the intrinsic function TRIM to be elemental.
Regression at FTN95 version 6.0: SIZE(x, dim) was failing for assumed-size arrays.
FORALL is now allowed to use the same index as an outer DO contsruct.
/CHECK was giving an access violation at runtime when the FORALL index was passed to it as an argument.
An exclamation mark in column 73 was giving a false line truncation warning.
A false runtimne error was being issued when using /FULL_UNDEF for a certain generic routine.
MAXVAL,MINVAL,MAXLOC and MINLOC intrinsics did not report a compilation error when used with assumed-size arrays.
USE ONLY was not hiding a MODULE subroutine.
DRAW_FILLED_POLYGON@ was failing when used repeatedly with a very large number of different colours.
ClearWin+: %th[ms_style] did not allow multiline tooltips.

New in Silverfrost FTN95 6.35 (Nov 21, 2013)

New in Silverfrost FTN95 6.30 (Nov 21, 2013)

New Features:
*.cs files can now be included in a DBK_LINK2/4 command line in order to transmit assembly attributes to the exe/dll.
/CHECK argument checking now extended to module subprograms.
/LINK with /DEBUG now activates /3GB in SLINK.
ASSEMBLEY_INTERFACE now allows ARRAY="REF" (default ARRAY="NET") to allow star-sized arrays to be passed only as a reference to the first element of each array in the argument list.
Clearwin+: Two new functions have been added to the library as an alternative or addition to %gr[user_surface]. These are CREATE_USER_SURFACE@ and SELECT_USER_SURFACE@. The associated %gr is identified by its Windows handle (see %lc) and the programmer must store the associated device context and DIB pointer.
CALL CREATE_USER_SURFACE@(width, height, hdc, ptr) !(inputs width and height and returns hdc and ptr - all INTEGERs)
ia = SELECT_USER_SURFACE@(hwnd, hdc, ptr) !(inputs all arguments and returns non-zero value on success)
Clearwin+: New standard callback HELP_LOOKUP added. This takes two character strings. The first is the full path of a .CHM help file. The second is the keyword that identifies the topic that is to be displayed. This keyword must be included in the .HHK file that forms part of a Microsoft project to compile the .CHM file. Note: HELP_CONTENTS can already be used with .CHM files.
Outline summary of bugs that have been fixed:
TYPE definition failed to propagate in a particular subprogram that was internal to the main program.
RECOVER_DIB_BLOCK@ had 2048 horizontal pixel limit.
A particular ALLOCATE statement reported and incorrect array rank.
PAD was not working in the RESHAPE intrinsic except for integers.
VAX initialisation statements failed when the list contained an array that was not the first item in the list.
Assignment via a pointer failed when pointing to an element of an array of user-defined type which, in turn, had array members.
Assignment to NULL using =>NULL() rather than NULLIFY was failing under .NET.
MAXLOC and MINLOC intrinsics could not be called directly in order to set an array index.
For arrays of rank one, MAXLOC and MINLOC now only return a scalar when DIM=1 is an explicit argument.
SET_SUFFIX@ and SET_SUFFIX1@ were only working correctly for extensions of length three.
Logical test for element by element character equality was failing for scalar against array constructor.
Clearwin+ Improvement: %`rs can produce unwelcome additional height with XP theme.
Existing option [no_additional_depth] used to restore old (non-XP) height.
Clearwin+: Documentation has been added for existing functions import_gif@ and export_gif@. These are similar to import_bmp@ and export_bmp@. Interfaces are now included in standard header files.
Clearwin+ Improvement: import_image@ has been extended to handle GIF files and resources.
