Andy,

Correct (WRT "...multiple if-then-endif scenario only allows one input file and will generate duplicate outputs when the criteria interesect.).

I handle this via post scan processing with Sean's perl script for now (multiple scans produce multiple lists, then I merge to see how many of them a single issue occurs in ... sorta like a DSN_3 or DNS_7 determination). Future plan is to use that database approach (access or excel) I eluded to earlier.

Clearly the best solution would be for Q+R2 to have all of these capabilities, however I view Q+ as a data provider and refrain from depending too much on its list processing capabilities. I've chosen not to belabor the parser and scan syntax at this time as it will likely have the undesirable effect of delaying release of Q+R2. I have been collecting thoughts on this subject with Q+R3 as my implementation target.

....I also wish we could define more then one output file allowing the generation of multiple lists from a single scan.

BTW: another advantage for nested ifs (or switch statements ala C++ or case statements ala Ada) is the increase throughput it affords... the scan (program) whould not spend time checking if something is red, blue, or green if it has already determined it to be yellow.
