MCRO(099) calls the subroutine with the specified subroutine number just like
SBS(091). Unlike SBS(091), MCRO(099) operands S and D can be used to
change bit and word addresses in the subroutine, although the structure of
the subroutine is constant.
When MCRO(099) is executed, the contents of S through S+3 are copied to
A600 through A603 (macro area inputs) and the specified subroutine is exe-
cuted. When the subroutine is completed, the contents of A604 through A607
(macro area outputs) are copied to D through D+3 and program execution
continues with the next instruction after MCRO(099).
