Sorry, but while Borland isn't 100% compliant, they are increasing their
compliance. I've ported code from v3 to v4 and now to v5. I've had to "fix"
non-compliant areas. 

Versions 5 *does* required that loop control variables be local. I had to 
change a number of global variables to local ones to make the code work.
(Not my fault, I didn't write the original code, and the guy who did is
normally working with COBOL and it shows!)
