(apologies for the LookOut! top-posting. In addition, I get the digest so all
list responses are delayed.)
Dave: while still a manual process, you could exploit the array itself to
track your list of indices. While my example had 4 pre-defined "TagNames" I
was looking for, you could just as easily insert your index values as you
encounter them. Look at 1) do TagNdx, 2) TagName=, & 3) Calendar.TagName.*
items below & you'll get the drift. There's also a similar construct using
ValueNdx and TagValue later in the snippet. I have no idea if this array code
is efficient for Rexx since it's processing under 2k lines in batch.
Any & all questions entertained. ciao (Ya know, if memory serves, I think I
got the idea of associative & multiple indices from Dave in the first place.

Much of my growth in this field has been slow and steady.
The Rexx associative array realization is one of the "aha moments" I still
remember.
What I'd really like (is it there and I don't know?) is a:
for "each" stem_var.
say "each"
if each = ....
other_stem.each = 'foo'
etc.
