Subprogram with call-by-value parameter transfer (PROC)

Function
A subprogram with call-by-value parameter transfer is defined using the PROC keyword
followed by the name of the program and a complete list of all the parameters expected by
the subprogram, with type and name. The definition operation must appear in the first
program line.
Call-by-value parameter transfer does not affect the calling program. The calling program
only transfers the values of the actual parameters to the subprogram.
Note
A maximum of 127 parameters can be transferred.
