ANYVAR Parameters
If a routine has ANYVAR parameters, its physical parameter order contains
one hidden parameter for each. In the physical parameter order, each
hidden parameter follows its corresponding ANYVAR parameter. The value
of each hidden parameter is the size of the corresponding ANYVAR
parameter (in bytes).
If the routine specifies the UNCHECKABLE_ANYVAR option, no hidden
parameters are passed for ANYVAR parameters.
The UNCHECKABLE_ANYVAR option is used when calling routines that were not
written in Pascal.

PROGRAM prog;
VAR
x,y,z : integer;
PROCEDURE p ( a : integer;
ANYVAR b, c : integer;
d : integer;
ANYVAR e : integer);
BEGIN {p}

END; {p}
BEGIN {prog}
x := 2;
y := 3;
z := 5;
p(1,x,y,4,z);
END. {prog}
