Re: Debugging COBOL ILE - a BUG?

[Jim Essinger <esinger@xxxxxxxx>]

Geir,

This has always troubled me.  It has been that way in ILE COBOL as long as 
I can remember.  If you don't access the variable in the program, you don't 
get to see it in the debug.  I believe it has something to do with the 
optimization that the ILE compiler does at compilation time.  It is VERY 
annoying at times, but I have not found away around it, other than to name 
the field in an operation in a part of code that will not be 
executed.  MOVE Y to Y seems to work, does not destroy the contents, and 
makes it available to debug.  I only use this during debugging, and then 
remove it from production code.
