Re: Matching Records

Booth,

It's the cycle: it reads records from the primary and all secondary files, evaluates which one is the next to be processed and then moves the data from that record to the program fields. So if *IN01 and *INMR are on, you have the data from the primary file and you know there's a matching record in a secondary file, but you don't have that data yet.

hmmm... I don't read the manual well enough sometimes, but I believe that the MR indicator, and the file processing, is such that the next 02 is always there, and known. Otherwise there would be no way for the program to know which record to grab next. In other words, when MR is on, then 01 and 02 are also on. If there is one 01 record and 5 matching 02 records, then MR will stay on while all six records are processed. If MR is off then we know we have a widow or an orphan.

Then again I could be wrong as heck. :)
