Re: Session or device error

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

Begging the question of why have two programs that are exactly the same, 
this sounds like the subfile has no records selected (i.e., it's an 
empty subfile).  The subfile's relative record number (defined in the 
F-specs) is *Zeros.  Condition the SFLDSP keyword on some indicator, and 
set this indicator *On or *Off before outputting the Subfile Control.


Now as to why two iterations of the exact same program would return 
different results.  Are there selectors in the program ("Start 
here...")?  Or do you just load the entire CUSTOMER table from beginning 
to end in both?  If the answer to the first question is 'Yes, but I used 
the same selector in each,' or the answer to the second question is 
'Yes,' then the programs are obviously not exact replicas if one returns 
the error and the other one does not given the same working parameters.
