I'm having this problem with variable substitution in arexx commands.
In this first code segment the variable "i" gets properly drawn into
the "show()" command:

--------- code seg #1 ------------------------------------

/* tests for number of TxEd's currently running */

do i = 1 to 10 /* assume there won't be 10 editors running */

  z = show("P","TxEd"i) /* translates to show("P","TxEd1"), TxEd2, etc. */

  if z = 0 then break
end

-----------------------------------------------------------
/* assume there are 3 editors running, TxEd1, TxEd2, TxEd3 */
/* therefore, when "break" occurs i=4 */

/* ---------   continuing  ------------- */

address command e  /* this will start a new editor, which will be TxEd4 */

/* NOW COMES THE PROBLEM */

address 'TxEd'i 'LOA' a  /* loa = load, a = filename arg */

        ^^^^^^^^
I can't get this substitution to work 
Have any ideas how to make this work?
I think I've tried everything...well, hopefully not  ;->
Actually, I was surprised the substitution in the first code seg worked.
Even if you use a variable for the address, the address command won't work.

k = 'TxEd4'

address k 'LOA' a  /* doesn't work */

Any help would be appreciated!
