Re: [U2] Comparing numeric strings
Still not that elegant but the quote function worked for me. 0001 a = '401.0101' 0002 b = '401.0101000' 0003 crt 'equal ' :a = b 0004 crt 'quote ' :quote(a) = quote(b) 0005 crt 'comp ' :compare(a,b) Output: equal 1 quote 0 comp 1 Cheers, Stuart -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Rob Sobers Sent: Saturday, 13 August 2011 03:11 To: U2 Users List Subject: Re: [U2] Comparing numeric strings Thanks all.

Re: [U2] Comparing numeric strings
COMPARE() works, just be careful if you're using it for sorting strings. Compiling and running the following test program: GET(ARG.) A ELSE ABORT GET(ARG.) B ELSE ABORT X = COMPARE(A, B) IS.LESS.THAN = (X LT 0) DISPLAY (IF IS.LESS.THAN THEN "less" ELSE "greater"):" than" LOCATE(A, B; FOUND; "AL") ELSE NULL IS.LESS.THAN = (FOUND EQ 1) DISPLAY (IF IS.LESS.THAN THEN "less" ELSE "greater"):" than" END Gives the expected results most of the time: >TEST 1 2 less than less than >TEST A B less than less than But give different results when the second parameter is a substring of the first: >TEST AAA AA less than greater than Apparently COMPARE() and LOCATE() use a different algorithm internally. LOCATE() gives results similar to SSELECT and SORT. rex Universe 10.3.7 Pick Flavor On Fri, Aug 12, 2011 at 1:19 PM, u2ug wrote: > Have you looked at the COMPARE() function ? > Does the trick under universe. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

Re: [U2] Comparing numeric strings
Hi, I think the SCMP command is failing because of the decimal place. If you take that out you will see it work correctly.
