Subprograms
Subprograms
A subprogram is a subsection of blocks within a program which can be
called from another block within the program. The subprogram blocks
are programmed once, but may be run multiple times. A subprogram
can also be mirrored. See Fig. I.45.
Nesting subprogram
Subprograms can also be "nested." For example, a subprogram can in
turn call another subprogram.
Labels
Labels are visual markers within a program that designate the beginning
and end of a subprogram (abbreviated in the program to LBL.)
Example: Insert label for subprogram. See Fig. I.46.
