Re: *PSSR subroutine and the call stack -- MIDRANGE-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Well - not at compile time. You CAN call the same subroutine from
different places and make it work, as long as a subroutine not calls
itself recursively (direct or indirect).

You can also implement recursive subroutines if you administer the stack
yourself. I did it once. Funny but an awfull lot of logic-administration
that you get free in other languages.

But now I get too nostalgic. Sorry. After all wee now have RPGLE.
