Thanks for all the suggestions.
I think the longname solution will be easy and probably work well.

But since I've been investigating, I found another suggestion on an oracle support board. I can't get it to work though, and dont really understand it. Just kinda curious at this point, so perhaps someone can explain what they are trying to do.

They suggest something like this.

Put password in a file, passwd.dat

exec < passwd.dat
CONCSUB apps/$1 <other arguements>

It's not presented very well, but does this give anyone any ideas?
I have no clue what the exec < passwd.dat is trying to accomplish, but it looks interesting anyway.
