  Well, I'm not sure I can visualize this problem poperly without actually
using UEdit and TeX, but your last paragraph may hold the answer.

  You can effectively start a script from a CLI using 'rx' by calling a
script from UEdit that in turn calls the 'texify' script. The script that
kicks everything off can be quite short, returning immediately, giving
'control' back to UEdit. Remember that scripts can also communicate with
each other, so if that is useful to you, you can do more than just start
texify.rexx

  In addition to starting the whole process, you can also use other scripts
at any point during the process to do various things for you. These can
be started by texify.rexx, and (I presume) by UEdit and TeX. I ran into
what may be a similar problem using TxEd and ARexx, where a script seemed
to hang when it was put into a Wait, waiting for a message from TxEd, and
I solved the problem by kicking off another script from TxEd to actually
send the necessary message.

Hope this leads to some success.
