RE: [COBOL400-L] reading a file organized by OPNQRYF

[Winchester Terry <terry.winchester@xxxxxxxxxxxxxxx>]

Rick,

We don't do a lot of OPNQRYF's feeding Cobol programs
so I can't help you much there, however, I noticed
you do not have an OPNSCOPE parm on your OPNQRYF statement.

This could bite you depending on how your job calls
are set up.  The majority of our jobs use OPNSCOPE(*JOB)
to ensure that the open query file doesn't carry over 
into another job.  

Terry
