Re: Can files be opened local to a "subprocedure"?

So far, in my tests, it appears that (at least at V6), simply moving the F-spec to procedure level requires me to treat the file as program-described, and define a structure to receive the record, but treating externally-described files as program-described is old hat around here. Apparently scatter-gather doesn't work for files declared at procedure level?

You're right that scatter-gather doesn't work for files defined in a subprocedure.

You can define the file as externally-described in the subprocedure. You do need to specify a data structure in the result field of the I/O operations, but it can't be "any" data structure. It has to also be an externally-described data structure for the same file.

Being able to use a data structure with an externally-described file is actually "new hat"; it wasn't available until v5r1 or maybe even v5r2.
