[U2] Date comparison
We have been experiencing this quite a bit and am not sure why we are getting mis-comparisions. Below is a simplified example of our issue B$CHECK.855.SENT: 51: IF ST.DATE # THEN B$CHECK.855.SENT: 52: IF ST.DATE 12-31-11 THEN B$CHECK.855.SENT: 53:PRINT PL:Date is less than 12-31-11...: : ST.DATE/ STRING: T r L=8 `01-20-12' We have this issue with programs and with SELECT statements throughout. When you qualify a date for this year to a date from 2011 it screws up. Barry Rogen Senior Programmer/Analyst PNY Technologies, Inc.

Re: [U2] Date comparison
Hi Barry, Unless I am mis-understanding your example, you appear to be doing this comparison using external format dates which is doomed to failure. They will be compared as simple character strings, left to right, until a difference is found. You need to do the comparison with an internal day number.

Re: [U2] Date comparison
Isn't your 2nd line of code going to be doing a string comparison on the date, not a true date (number) comparison? I always do an internal format comparison of dates. If you need to do string comparisons, you d want them in -MM-DD format, but I advise against it.

Re: [U2] Date comparison
You should always work with dates/times/numbers in internal format and only convert them to external format for display. Wherever ST.DATE came from, it should have been converted using ICONV: ST.DATE=ICONV(ST.DATE,D) and have a value of 16091 (assuming that the 12 means 2012 and not 1912). The comparison would be IF ST.DATE ICONV(12-31-2011,D) THEN The actual data stored in a file should be in internal format--never ever external. When using query LIST/SELECT, make sure the dictionary is right justified and has a date conversion: 0001 D 0002 1 0003 D4/ 0004 DATE 0005 10R or in a 10-line dict: 0001 A 0002 1 0003 date 0004 0005 0006 0007 D4/ 0008 0009 R 0010 10 If the date conversion is being done by an type expression instead of a conversion, or by a correlative on the 8th line of a 10-line dict instead of by a conversion on line 7, queries will likely not work. When you use a query like: SELECT INVOICE-FILE WITH DATE.DUE 01/01/2012 the query processor uses the conversion code to convert 01/01/2012 into internal format, and then compare against the internal data on file. If you don't have data in internal format, then this is just a string comparison, and 01/01/2012 is NOT equal to 01/01/12, and 02/01/2000 is great than 01/01/2012.
