How to get UIC

cckcwong — Wed, 03 Sep 2008 02:16:07 GMT

I want to get the UIC of user account in numeric format from my VAX BASIC program. Which runtime library function should I use? Please help.

For a general purpose identifier to ID service you would call SYS$ASCTOID.
See $HELP SYSTEM $ASCTOID

For the UIC of the current process you would either call SYS$GETJPI with an item list requesting potentially many values or LIB$GETJPI for a simple single item. Both would be called a process ID = 0 and ITEM code JPI$_UIC. JPI$_UIC is defined in $JPIDEF (as 772).

See the basic user manual and GOOGLE for online examples.
Just google for: +openvms +basic + lib$getjpi

You'll find places like:

Good luck!

cckcwong,

I agree with Steven and Hein. However, it is more important to ask: Why does the program need the UIC?

There are very few instances in which the UIC is actually needed by a program. In most cases (e.g., file ownership) the best approach is to let OpenVMS propagate the information automatically.

What task is the program actually attempting to do?

I have attached a BASIC sample that has been in use for many years at a site which I support.

It accepts the username in various formats (see the comments in the source)

Terse questions beget terse answers. Often correct answers, but surprisingly often answers that are either less than the best available for the local requirements, or answers that are outright wrong for the particular situation.

Please consider providing some background details.

I can think of a half-dozen different ways to answer your stated question here, depending on exactly what you're up to here. Most of which will probably be wrong for what you intended.

As for the general answer for seeking code examples.

Maybe some DCL will help ..

$ write sys$output f$identifer("system","Name_to_number")

$ write sys$output f$fao("!%U",f$identifer("system","Name_to_number"))
