Builtin to determine level of recursive calls

When using recursive procedures, it would occasionally be useful to know if the procedure currently active is called directly, or recursively, and in the latter case, provided such information is available in control blocks, at what level of recursivity it runs.

A new builtin, similar to the existing "ALLOCATION", which reports on the number of generations of controlled storage that can be accessed, a "RECURSION()" would report the level of recursion, or just that the current invocation is a recursive one.

    this is, in general, not so doable on all platforms and is probably not worth adding to the language

    might be nice, but using the current language features one can easily determine the number of recursions, so i wonder if it's worth adding it to the language/compiler (i tend to say "no" :-)).

    in the following code fragment (not compiled & tested thoroughly) "foo" is called recursively 10 times,
    call rec();
    rec: proc();
    dcl counter bin fixed(31) controlled;
    if allocation(counter) = 0 then do;
    allocate counter;
    counter = 1;
    end;
    counter +=1;
    if counter > 9 then return;
    call rec(); /* recursion */
    end rec;
