I think we need some clarification -- un peu préciser le contexte!

What is the syntax of the way "&500" (or other) is used to
identify the data?

What code do you use to recognise "&500" (or other) as an identifier?

It might be possible that something in your code causes "&" to
be recognised as the R operator for logical conjunction which
(depending on your code) returns FALSE in some cases; but it is
difficult to see how "xxxx&500" can be TRUE, but "xxxx&501" FALSE!
