6.26 Call %SP Modules
6.26.1 Call an %SP Module sp
Syntax
sp(moduleno{, argn}6 ...)
moduleno: Number of the %SP module to be called.
argn: Optional argument.
Calls an %SP module (%SP0, ..., %SP255) and passes it any arguments via the stack.
Operation
The module number must be between 0 (call to %SP0) and 255 (call to %SP255).
The arguments are extended to 32 bits and placed on the stack. The call is then made.
The total number of arguments (including moduleno) must not exceed NBM_PARAM (set to 7).
A call to function cpyarg() at the start of the called module allows the arguments passed via the stack to be recovered.
