Re:   An Alternative to SIMCVT.BAS

I found SIMCVT.BAS rather frustrating since I do most of my SIMTEL20 FTP work
from a VAX, and found it irritating to have to download SIMIBM.IDX to a PC,
run SIMCVT.BAS, re-upload SIMIBM.LST and then print the sucker from the VAX.

Therefore I hacked a little piece of code to munge the SIMIBM.IDX file on
our VAX using SPSSx. It has been tested on SPSSx 3.1 under VAX/VMS 5.0-2 and
seems to run fine.
