Re: Error using a function -- MIDRANGE-L

As Mr Spock has often mentioned,
"When the logical is not the answer, then we have to look at the illogical"
(or words to that effect)
Is there by any chance a different object type named INVENTORY in the library 
list?
If so, can you rename it and try again.
Like I said - illogical - does NOT make sense - stupid idea.
But have a look see.

Same message with ONHAND
INVENTORY in ROB3 type *SRVPGM not found.

Rob,

One thing that stands out to me is the way you specified the name of
the procedure. Procedure names are case sensitive. Did you actually
use OnHand? if you did try ONHAND, which is what RPG actually
exports. I think that should fix your problem.
