The files need to compile ShowPic NDA v5.4 are:

ShowPic5.46.Pas   which is the interface routine.
LoadPic5.46.Asm   which is the routine to load pictures.
  LoadPic5.Mac    macro file
SavePic5.40.Asm   which is the routine to save pictures.
  SavePic5.Mac    macro file
ConvPic5.40.Asm   which is the routine to convert pictures.
  ConvPic5.Mac    macro file
Load325.43.Asm    which is the routine to load 3200 color pictures.
  Load3200.Mac    macro file
  Palette.Asm     palettes
  Palette.Asm2    more palettes
LoadGIF5.46.CC    which is the routine to load GIF pictures.
  Std.H           header for LoadGIF
  Errs.H          another header for LoadGIF

The version of the source code reflects the last release version number
that the source was changed for.

********************************************************************************

  The interface file changes have been corrected.  I now use custom calling 
procedures in the source code for SFMultiGetFile and OpenResourceFile.

********************************************************************************

To compile the NDA, exec the file MakeShowPic5.4.

This program requires ORCA/Pascal, ORCA/C v1.1 and ORCA/M to compile.  The
Pascal source is currently written for ORCA/Pascal v1.2.4 or later.

Feel free to use these routines in your projects, but pass the credit on.
If someone can overcome the ROM 03 quirk (not being able to catch the
button clicks) they are encouraged to recompile this and it will be 
version 5.5.  I'm working on further revisions, but will be out of touch
for a month or two.
