MCH1210 error in QGYOLSPL api

I have the following program (subset of the actual program but this will
compile for demonstration purposes) using the QGYOLSPL api to retrieve a
list of the spool files on our systems. When I run the program it is
crashing with escape error message MCH1210 Receiver value too small to
hold result which is not listed in the documentation for the QGYOLSPL api.
We are at v6r1.

Does anyone have any thoughts as to why I am receiving the error message?
I have tried numerous things including copying from posted on the net
and without success I am now definitely into the WAG stage.

Thanks,
