VARGSIZE returns the number of bytes that a variable would occupy
on the stack if it were passed byvalue.
>>-VARGSIZE(x)-------------------------------------------------><
- x
- A variable of any data type, data organization, alignment, and
storage class, except as listed below.
x cannot be:
- A BASED, DEFINED, parameter, subscripted, or structure or union
base-element variable that is an unaligned fixed-length bit string
- A minor structure or union whose first or last base element is
an unaligned fixed-length bit string (except where it is also the
first or last element of the containing major structure or union)
- A major structure or union that has the BASED, DEFINED, or parameter
attribute, and which has an unaligned fixed-length bit string as its
first or last element
- A variable not in connected storage
VARGSIZE(x) returns the number of bytes that x would occupy on
the stack if it were passed byvalue. This value will be at least as
large as SIZE(x); it will be larger if the value returned by SIZE(x)
needs to be rounded up to a 4-byte multiple.
VARGSIZE is meant to be used only inside a procedure whose last
parameter has the LIST attribute.
