I have a problem with an XFCN for SuperCard. Basically, it maintains a
counter in a global variable (THINK C) which is incremented every time
the function is called and the value is returned.
The problem is that it SOMETIMES returns a random (huge) value instead of
the proper one. It then either continues with the correct value or
with the new, random one. I can guess that it might mean trouble relying
on global values to be maintained across calls to an external. In HyperCard
I could (I think) fixed this by setting the "locked"-bit of the resource,
but this is not possible in SuperCard. Does anyone have a solution to this?
Thanks,
