I'm 99.9% sure it's your fault and not Turbo Pascal's.  You probably have
uninitialized pointers and are writing over the top of the area in memory where
the typed constants are stored.  When you changed them to variables they were
stored in a different place, so they didn't get written over (but something
else probably did!).   This type of behavior can also occur if you pass too
small a buffer to some procedures such as GetImage, BlockRead, etc.  Use the
debugger (or put in lot's of writelns) and find out exactly when in your
program the constants are being changed.
