FTN95 Revision History

See also: Plato Revision History

Version 5.50

New Features:

• A new command line option /RAGGED_ARRAYS has been added for use with /CHECK and /CHECKMATE. This option prevents a runtime failure when a non-rectangular array is passed to a subprogram as is the case with some BLAS/LAPACK routines.
• An optional new memory model in salflibc.dll has now been made the default. The environment variable FTN95_NEW_MEMORY can be set to FALSE in order to switch this off.
• Plato is now fully integrated with SDBG when this feature is switched on in the Options dialog.
• Plato can now print files using syntax colouring.
• ClearWin+: A new option has been added for %cw called [local_font] that causes %cw to use the current %fn and %ts.
• ClearWin+: A new option [popup] has been added to %gr so that a %pm menu appears with %gr[full_mouse_input].
• ClearWin+: Additional keyboard characters have been added for %ac including plus (+) and minus (-) characters.
• ClearWin+: A new CLEARWIN_INFO@ information string has been added: OPENGL_ALIVE

Outline summary of bugs that have been fixed:

• Improved Windows 7 compatibility
• Several issues that are generally seen on x64 operating systems with large amounts of RAM have been fixed. These issues manifested themselves as out-of-memory errors and unexplained floating point exceptions (that were in-fact underflows)
• Fixed a problem with building on Windows 7/Windows Server 2008 and deploying lower versions of Windows where certain system functions could not be located in kernel32.dll.
• /EXPLIST was failing when used with a large file and /CHECK.
• SELECTED_INT_KIND and SELECTED_REAL_KIND did not respond to /ALT_KINDS.
• When not using /LINK a bad object file was sometimes created despite reported compilation errors.
• An access violation occurred when a constructor for a user defined type was assigned to an integer.
• Windows NT text console commands (WCREATE@ et al) now function correctly on consoles with more than 50-lines of line buffer

Version 5.40

New Features:

• Windows 7 compatibility
• New comment embedded directive STDCALL added for use before an EXTERNAL statement.

• New routine DOWNLOAD@ added. This is similar to READ_URL@ but reads into memory.
• Many of the /CHECK features are now available when using /F_STDCALL.
• ClearWin+: %ht now accepts JPEG images.
• ClearWin+: %ht now uses a standard callback COPY_TEXT in order to copy all of the text in the current HTML page to the clipboard.
