Hmmm.... pascal, fortran and C???
Here's a proggy to convert shapes.pas into pure 100% Pascal..
Mail me if you have any probs....
Instructions are in the .TXT file this produces..

XWell... after the complaint about SHAPES being in PASCAL,C AND FORTRAN,
XI decided to convert it into pure PASCAL.
X
XWhat (dis-?) advantages this may have, I have no idea....
X
XThe mod is very simple, and uses the EDT editor to replace some lines in
Xthe SHAPES.PAS file...
X
X***WARNING***
X
XThe SHAPES.PAS file **MUST** be in the original format that it is in
Ximmeadiatley after it has been decoded from the SHAR file
X
XTo convert the program simply type @SORT_SHAPES
X
XThe files SHAPES.PAS, SORT_SHAPES.EDT, SORT_SHAPES.COM and SORT_SHAPES.PAS
Xmust be in the current directory for this to work......
