Explanation
Presenting Parameters to the Called Program
A formal parameter in the called program can have one of two attributes: value or
reference. Depending on the description of the actual parameter in the calling program
and the description of the formal parameter in the called program, the compiler
generates code to convert the value of the actual parameter to match the description of
the formal parameter

Parameter Explanation (page 1 of 2)
VALUE When a formal parameter in the called routine has the VALUE attribute
and is numeric, the compiler generates any code necessary to evaluate
the actual parameter, convert the value to the expected representation and
scaling, and pass the value to the called program.
When a formal parameter has the VALUE attribute but is nonnumeric, the
compiler generates code to pass the value to the called program.
When an actual parameter in the calling program is a literal or an
arithmetic expression, the corresponding formal parameter must have the
VALUE attribute.
