Thank you for all the comments, but I have found the problem and
corrected it. For those who are interested :

  The fault is that my window name was TOO SHORT!!  In the PRM it states
that:

"If you use wildcards .. there must be enough space to put the full name
of the template in memory"

However, it seems that it is necessary to have enough space for all the
template names preceding the one you want in the file.  I changed the
name of the ELM window to ELMW (thus forcing BASIC to allocate more
stack memory for the string, (5 bytes - E,L,M,W,\0)) and everything
worked fine.

 The problem is basically that BASIC wasn't allocating enough stack
space to hold the string when doing the SYS call.
