RE: Additional Error Specs from C-Proc. 'system'

["Smith, Nelson" <NSmith@xxxxxxxxxxx>]

I've always used the "pretty wrapper" around QCAPCMD method myself, and now
that you bring it up, I remember it was rather messy to get it working
originally.  I guess what I was asking is if you already have a clean
wrapper around QCAPCMD, is there any real benefit to using 'system'?  And I
think you said, "no".  Right?
