If someone was foolish enough to write their own one, perhaps
having it call the built-in MVSVAR() wouldn't it be possible for
an exec to call the local one in preference to the built-in one?

Guys,
the code receives a text string which may contain one or more symbols, denoted
by prefix "&" and optional suffix ".", as per my reading of how Z/OS handles
symbol substitution.
Say we have these symbols defined in IEASYM00:-

Hi,
I am writing a general subroutine that would replace system symbols in any text
string.
I had a fairly complicated piece of code to do the correct symbol replacement,
including possible symbol concatenation, obeying all the replacement rules I
could remember. My code still had somewhere to
