Subprogram call with parameter transfer
In the main program you call the subprogram by
specifying the program name and parameter
transfer. When transferring parameters you can
transfer variables or values directly (not for VAR
parameters).
Example:
N10 DEF REAL LENGTH,WIDTH,DEPTH
N20 …
N30 LENGTH=15.3 WIDTH=20.2 DEPTH=5
N40 BORDER(LENGTH,WIDTH,DEPTH)
or
N40 BORDER(15.3,20.2,5)
Subprogram definition must match subprogram
call
Main program
N30 LENGTH=15.3 WIDTH=20.2 DEPTH=5
N40 BORDER(LENGTH,WIDTH;DEPTH)
or
N40BORDER(15.3,20.2,5)
Both the variable types and the sequence of transfer
must match the definitions declared under PROC in
the subprogram name. The parameter names can
be different in the main program and subprograms.
Example:
Definition in the subprogram:
PROC BORDER(REAL LENGTH, REAL WIDTH, REAL DEPTH)
Call in the main program:
N30 BORDER(LENGTH, WIDTH, DEPTH)
