The other reason for avoiding strtok() is that it is not
re-entrant.  But since RPG programs are not re-entrant
anyways, that's not a valid reason for not using strtok().

On the other hand, since strtok() uses a static internal
variable, you cannot use strtok() multiple times within a
nested loop.

The best way to avoid problems is to just use the C
run-time function strtok_r() instead.
