This program shows how to sort an input file (formal designator INPF)
to an output file (formal designator OUTF) using
the SORTINIT intrinsic call.

In the example execution, the input and output
files are associated with the terminal ($STDIN and $STDLIST):
:FILE INPF=$STDIN
:FILE OUTF=$STDLIST
:RUN PROGRAM;MAXDATA=12000
character
credit
DEBIT
:EOD
credit
character
DEBIT
