Craig Bennett pointerd out that TEST = '\AF1\CK1\CK2\H\LHC\MP\NU1\NU2\TK1\TK2\' IF INDEX(TEST,'\':F200.SCHEME.CODE:'\',1) THEN THAT = @FALSE *can* generate a false positive if F200.SCHEME.CODE contains an embedded slash. In this case it can't, because the F200.SCHEME.CODE is validated on entry against a list of codes (whew!) The super long string I started with is from a program to decide whether or not to show something on a printout. I suppose I could quibble and say it is actually a true positive... but no, Craig got me proper. My bad.
However, this brings up a good practice thing to note. The seperator must not be 'enterable'. So that makes INPUT a bad idea. If you want to try out an alternative, I just put http://www.pickwiki.com/cgi-bin/wiki.pl?action=edit&id=GetKey up on the wiki. My problem was that the Asus eeePC does not seem to be a proper xterm, so I reproduced most of the functionality of QM's keycode() input. =========================================== Looking back, I feel I may have defended the INDEX function more than I wanted. My own code generally looks like this ENDWORDS = 'IF\OPEN\OPENSEQ\READNEXT\READ\READU\READV\READVU\' ENDWORDS = ENDWORDS:'MATREAD\MATREADU\LOCATE' CONVERT '\' TO AM IN ENDWORDS and I use the classic form LOCATE(WORD,ENDWORDS;POSN) THEN Regards, Keith PS: The extra line is solely to prevent wrapping on an eighty-column terminal. I value my concept of readability above efficiency. ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
