I'd like to take issue with that, Brian. As far as I am aware what you say is
right for a LIT equate, but not for a TO equate.
With a TO equate the compiler evaluates the expression, so that the literal
string (in the current example) "ABCD~EFGH" would be what was substituted
throughout the code.
With a LIT equate the expression itself is substituted.
Please correct me if I'd got that wrong - I'm not anywhere with access to VLIST
at the moment.
Regards,
Ray
