Could you post (or mail) an example? Without one, it gets rather difficult
to track down.

My guess would be that the variable is getting overwritten by something
else. Enable range checking and try again. Also, try changing your
write(lst,var) to write(var) rather than inserting a write(var) in
the code. This can make a big difference.

Finally, if you have version 5 step through the code with the debugger.
And set up a watch on the variable. Then you'll know where it gets clobbered
and only have to figure out *why*.
