Hi Don,

The .profile script is only intended to be run during interactive logins.

On a "real" Unix system, .profile is only run for a 'login shell', 
meaning the user is signing into the Unix system.   It's not run otherwise.

Consider .profile as analogous to CHGUSRPRF USRPRF(you) INLPGM(foo). 
When you set up an INLPGM for a user, it's only run once when the user 
signs on.  When that user submits a job, et al, it does not run the 
INLPGM again for the submitted job.  It's only run when the user starts 
up interactively.

That's the behavior that .profile is supposed to have on a Unix 
system... so IBM implemented it the same way in QShell.  A submitted job 
doesn't run .profile, but an interactive login does.

Note certain other Unix shells (csh and tcsh, in particular) have two 
separate startup scripts....  one that runs every time a new shell is 
started, and one that's only run at initial login.   However, the bourne 
shell derivatives (sh, ksh and bash) don't work that way.... they only 
have .profile, and it's only run for interactive logins.  And QShell 
appears to be patterned after ksh (korn shell.)

Personally, I'm not crazy about the QShell default of only having 
/usr/bin in the PATH.  So I ran ADDENVVAR with LEVEL(*SYS) to change the 
default PATH so that it includes /usr/local/bin as well as some other 
folders, and my PASE stuff.  And because it's set at system-level, it'll 
automatically apply to all users, whether interactive or batch.
