Jim, the C thing you're thinking of is a char *
parameter, that is, a pointer to character, where the
pointer is passed by value.  The RPG equivalent of that
is a pointer passed by value, or a character variable
passed by CONST or reference.  What we're discussing
here is passing the character value itself by value,
loading all the bytes of the character value onto the
parameter stack.
