Actually, "<>" gave me the same false positive that "=" did. Changing the
comparison to strictly equal worked fine.
I am writing a rexx exec to parse some assembler listings to compare field
offsets in DSECTS across product releases. For the intent of my compare,
comparing the "0000E0" and "0000E8" as two strings was my intent. However,
rexx decides, for whatever reason, (probably because they "can" be numeric)
that they are not strings.
(I'm just happy it also doesn't consider ("zero" = "oh") to be equal too!)
Converting the offsets to hex or decimal would have also avoided the
problem, but it was overhead I didn't want to spend.
