I agree that an @IF or @IFEQUAL should be used, but I disagree about the quotes. In T2K, <@CALC "'39149E20021231'='39006E20021231'"> = 1, but <@CALC "'39149Z20021231'='39006Z20021231'"> = 0. The substitution is still taking place, despite the single quotes.

I think Anthony has run into a limitation of the math library - the thing that evaluates <@CALC> expressions. This sounds vaguely familiar... I think <@IFEQUAL> is the tag for this problem. It works on big things. On Tue, 18 Mar 2003, Kevin Quinn wrote: > 'E' is a defined CALC variable. Unless you're planning on using > natural logs, don't use E.
