No. $(call) functions can be recursive; in fact, some of the most useful invocations of call are recursive. aa> i am assuming the difference could be, for call, $1 could contain aa> the CMD again, or something like that? Sometimes; usually its the function definition that calls itself recursively. aa> even if exp_count > 0 is needed, EXP_COUNT_MAX is proving to be aa> too big a value.

If you look at the test suite in the functions/call test, the first one will fail if you set this to 0. -- ------------------------------------------------------------------------------- Paul D.
