Re: Subfile hang

All good reasons for using a FOR loop instead of a DO loop, imho. Lots of typical *duh* errors just disappear with the FOR loop.

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.
