Paul, I suspect that I have been sensitized in this respect by my favourite drawing program, CorelDRAW!, not supporting previous version files. Doesn't matter at all to new customers, matters a lot to 'old faithfuls'.
A couple of years ago I found the paperwork from when I attended the launch of Clearwin. I forget now, was it 1992? So the DBOS graphics got superceded a very long time ago. The legacy was perhaps the legacy of a legacy of a legacy!

John-Silver,
you might want to look at the online help of ftn95 where /Define and /CFPP are both mentioned.
Sorry for the confusion. Option "/Define DRAW_TEXT 1" together with option "cfpp" is used to make line
Code: |
CALL DRAW_TEXT@('DRAW_TEXT@',100,200,RGB@(0,0,0))
|
seen by the compile step (or not). Option /cfpp means that the compiler first preprocesses the code before compiling it. Option "/Define DRAW_TEXT 1" makes that the code following line "#if DRAW_TEXT" up to the next #ENDIF is active after the preprocessor step. This has nothing to do with the semantics of CALL DRAW_TEXT@. It is only used to make the code line containing "DRAW_TEXT@" be used by the compile step or not.
If option "/Define DRAW_TEXT 1" is missing it is the same as if you would have decommented the line containing "DRAW_TEXT@". You need option "/CFPP" because otherwise ftn95 would complain about the #IFDEF.
Regards,
Dietmar |
