RE: Subfile hang

I think it may be that, it did find 2 lines but then hung, I am
debugging it, but it's a large bear of a program.

Thanks everyone!

=> Sounds like it's in a loop cycle trying to do a CHAIN using the
subfile record number, but it's not incremented (staying at zero), or
there's no test to leave the loop on a number that's not returned.

For reading subfiles by record number:
(X) You have to clear the field that you're using to loop and read the
subfile.
(X) Initialize a value to start from in that field, 
(X) Increment the record number field you use to CHAIN with each loop, 
(X) And test for LEAVE-ing the loop, whether it's a not-found condition
(NRF) on the CHAIN, or a maximum that we have from when we filled the
subfile.

Anyway, those are things to look for when you get an error like that.

HI, I was testing a subfile program and noticed this error message.
Interesting in that I had changed the input data that I had previously
been using and instead of one or 2 of these messages on the job log,

and

not effecting the program, the program hanged and it produced several
thousands of pages of this message. I am looking at what caused all of
this, perhaps there is some basic cause that I am not seeing?



"Message . . . . :   Subfile record not found.
