Hey all, In universe 10.1 how can I verify that a file pointer passed via a subroutine param is valid? I have a subroutine that is called with several file pointers but it is possible to be called without opening a file and the subroutine would check if the file pointer is empty and if so open the file.
The problem is that my check IF F.PTR = '' THEN Is erroring out with a invalid data type error message when the file pointer is passed in (instead of being null). I know that I can make all the calling programs open the needed files BEFORE calling the subroutine BUT if its possible to somehow have the subroutine check and open it if its (empty the file pointer), I would prefer to do that. Thoughts/suggestions welcome Thanks! dougc ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
