SBS
Function
SBS(091) calls the subroutine with the
specified subroutine number. The subrou-
tine is the program section between
SBN(092) and RET(093). When the sub-
routine is completed, program execution
continues with the next instruction after
SBS(091).
A subroutine can be called more than
once in a program.
Subroutines can be nested up to 16 lev-
els. Nesting is when another subroutine is
called from within a subroutine program,
such as shown in the following example,
which is nested to 3 levels.
