Wendy,

No guarantees, but check for mismatched parameters. Do you call any 
subprograms? If you define a parameter as Char(1) and the called program 
updates it as if it were Char(10), it will trash 9 bytes of storage that belong 
to something else in the calling program. I tracked this situation down once by 
examining a storage usage map. I'm not even sure how to print that any more.
