I have at least two problems with a program that changes various fields
of a given uaf record. If anyone can help, I'd appreciate it...

First, I'm running V4.4 of VMS on an 8500 system.

sys$getuai seems to work just fine but sys$setuai seems to return a 
rms error, record not locked, when I try to change a field of the uaf
record associated with the process issuing the call. The process can
use sys$setuai to change fields of other records, just not its own.

How do I set a password for a given uaf record? Even if sys$setuai
would work all the time, I can't find a system call to encrypt (hash?)
the password. I see LGI$HPWD in the microfish but I don't know if that
is what I need or how to call it... What I want to do is copy a uaf
entry, changing the userid. But that makes the password invalid.

I don't think the authorize program is the answer as I need to install
this particular program with privs and have everyone have access to it.
At least, I can't think of any way to use authorize except maybe to set
up a server process that can run authorize in a subprocess and can be
logged in under a userid that has the appropriate privs. I'm trying to
avoid that.

Thanks in advance...
