You need to define your SFLPGMQ variable as 276 bytes (instead of 10),
and use a qualified procedure name. ie:


Bytes           Value
------  -------------------
1..256  ILE Procedure name
257..266        ILE Module name
267..276        ILE Program name

All values are left adjusted, padded with blanks.

I can dig up an example if you really need one, but all you'd see is
some code retrieving the module/pgm names from the PSDS, and loading the
SFLPGMQ variable accordingly.

This is documented in the Infocenter:

Scan down the page to the SFLPGMQ keyword.
