CALLs to other programs. When calling a subprogram with USING try to specify as few parameters as possible. Each parameter passed requires an individual BLL cell to be allocated in the called program and may require additional registers to be used.
here, what is BLLcell(base locator for linkage )? explain in detail

So someone gave you advice to keep the number of USING parms to a mimimum, right?
I never heard of that before. Perhaps there is merit to this but I must confess my suspicion that it is not correct. I would reject that advice until the reasoning behind it was clearly explained to me.
If a design calls for 5 USING parms then I would simply use 5 parms. I would never think to reduce this number to - say 2 parms - just to keep the number low. I don't see the reason...
