Two problems:
        1) Missing error code definition on the prototype (7th parameter).
2) MainStgOS is not LIKE(QIMO0300). It is simply a chunk of storage. You could probably code it like MainStgS or specify OPTIONS(*OMIT) and pass a null pointer. Note: This won't fail but is misleading.
InputImageS is either LIKE(QIMI0100, QIMI0200, or QIMI0300) depending on the input source being used.
OutputStGS is either LIKE(QIMO0100, QIMO0200, or QIMO0300) depending on the output source being used.
For your requirements I would expect input QIMI0100 and output QIMO0200 should do the trick. Pass an empty variable or *OMIT for the 5th parameter. 

Also change all the B data types to I in your data structures.
Note: I don't see why the API call would fail with a pointer error. What program and statement did the pointer error occur on?

Simon Coulter.
