The biggest problem with this is if I recall correctly, the user id is
encrypted with the password with a variant of DES that has a slight twist
from the published DES algorithm. That is why there are two types of DES
encrypt calls in the RACROUTE REQUEST=EXTRACT macro; ENCRYPT=(data
addr,DES) and

You can't calculate the password from the stored value - as far as I
know that is still the c
