Re: calling commands in unknown (at compile time)

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

May I add another caveat or two?

I've been through situations as described here.  The library (say, LIBA) 
may or may not, as Darrell said, exist in the library list.  If it does 
exist, it may occupy any position in the library list (1-n).  After 
deleting and adding it, though, it is blatantly in position numero uno.


This may not be a good thing later on.  If this is a batch job, it 
*probably* doesn't matter.  However, if it is an interactive job, it 
*may* be perilous.  If LIBA was already in the list (say, #7 on your hit 
parade), leaving it at #1 *could* skew later jobs.


The original library list needs to be saved and, after you're through 
with LIBA (as #1), restore the original library list so that things are 
back where everyone is expecting them.  Another way to do this for an 
interactive job is to simply issue the SIGNOFF command at the end of the 
job (if you can wait that long) since a new log in will set up the 
library list as intended. 


Thanks.
