(4) Flexible management of subroutine programs
(a) Subroutine program sharing
The number of steps in a program can be reduced by sharing subroutine programs.
In addition, creating and managing programs become easier.
Subroutine programs can be created within the same program and called. Subroutine programs in other pro-
grams can also be called by using the common pointer.
