In the main program you call the subprogram either
with address L and the subprogram number or by
specifying the program name.

or
N10 SPIGOT_2
Main program
N10 L47
or
N10 journal_2
Subprogram
Subprogram with parameter transfer,
declaration with EXTERN
Subprograms with parameter transfer must be listed
with EXTERN in the main program before they are
called, e.g. at the beginning of the program.
The name of the subprogram and the variable types
are declared in the sequence in which they are
transferred.
You only have to specify EXTERN if the subprogram
is in the workpiece or in the global subprogram
directory.
You do not have to declare cycles as EXTERN.
EXTERN statement
EXTERN NAME(TYP1, TYP2, TYP3, …)
