I believe that you need to specify the UIC for the created process and pass
it in the parameter folloging the process name.

You might also consider creating a mailbox and and pass the unit number of
the mailbox in the second to last parameter to sys$creprc, then read from
the mailbox to get the exit status of the detached process.

If you are interested I could send you a bit of code as an example.

Hope this helps.
