I thought I'd try "411 for the HP 28S", labeled a "Directory Assistance System" written by Tom Affinito in 1988. The 'BUILD' command follows:

Code:

BUILD        CREATE A NEW WORKSPACE

            'name'  :

    << HOME ->411 DUP O->S "UTIL" + -> n n.s

        << IF VARS n POS THEN "NAME IN USE" 1 DISP BOOP

           ELSE 'WK.LS' DUP EVAL n + SWAP STO

            "<>" + STR-> n STO

            UTIL

            n.s DUP S->N CRDIR STR->

            WORK CRDIR

            << WON >> SWON STO

            {} SU.LS STO

            MAIN

           END

        >>

    >>

I get a "Too Few Arguments" error on "<>", line 4. Does anyone know what the symbol "<>" represents?

Update: I stumbled upon another source for this program. Line 4 is replaced by

Code:

"<<UTIL " n.s + " WORK SWON>>" + STR-> n STO

All is well.
