I'd do this with a subroutine record.  The input parameters would go to ao 
records, which would hold the paramenters until the subroutine record 
processed, but _not_ be out-linked or forward-linked to the subroutine record. 
The subroutine record would reference the ao's through the inpa through inpl 
fields.  The subroutine record could be made to process by a caput to the PROC 
field.  The subroutine code would download the chips based on the input 
parameters which would appear in the a-i fields.
