That looks like some MUF code I've seen (I never had a MUF flag on my old characters, so had no privilege to write in MUF -- MPI was available to all, and even it had some links to MUF operations using similar magic numbers). That, or attempts to use SYSTEM RPL on an HP calculator. Normal "user" programs, using user commands (those accessible via keyboard/menu) all include validation calls on their input arguments. Using system RPL one can write programs/functions that check the arguments once at the beginning, then assume all parameters will be of the correct type, and bypass the validation on function internal operations. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
