Note
The call-by-reference parameter transfer is then only necessary if the transferred variable was
defined locally in the calling program (LUD). Channel-global or NC-global variables do not have
to be transferred, since these cannot be accessed directly from within the subprogram.
Syntax
PROC <program name> (VAR <parameter type> <parameter name>, etc.)
PROC <program name> (VAR <array type> <array name>, [<m>,<n>,<o>],
etc.)
Note
Up to 127 parameters can be transferred.
Meaning
PROC: Definition operation at the beginning of a program
VAR: Keyword for parameter transfer via reference
<program name>: Name of the program
<parameter type>: Data type of the parameter (e.g. REAL, INT, BOOL)
<parameter name>: Name of the parameter
<array type>: Data type of the array elements (e.g. REAL, INT, BOOL)
<array name>: Name of the array
