Your original queston illustrates well the very reason I ignore a number of the built-in verifications routines. My opinion is that you're much better off coding your own verification and in doing so, implimentin whatever restrictions you see necessary.
yeah, we have our own verifydiff function that points to a filter file. The filter file will ignore certain lines that MatchStr is true on. I use matchstr so I can put wildcards in my filter. This is handy for output files that specify the data and time.
