Can anyone come up with a smart way of telling me if all values in a series are equal? The length of the series ranges from 1 to potentially about 200+ vID/value pairs (although in practice the longest series currently counts 15 pairs)

The format of the series is '{X-' followed by ID (3 characters)/space/number (sign+2digits)/space sets, so e.g.

Code:
{X-AA  +00 B   +00 CC  +00 D   +00
{X-AA  +00 B   +00 CC  +00 D   +00 E   +00 FF  +01 G   +00
{X-AA  +00 B   +00 CC  +00 D   +00 H   +00 II  +00 JJ  +01
{X-AA  +00 B   +00 CC  +00 D   +00 H   +00 II  +00 KK  +01 LL  +01 JJ  +01
{X-AA  +00 B   +00 H   +00 II  +00
{X-AA  +00 B   +00 H   +00 II  +00 JJ  +01 CC  +00 D   +00
{X-MM  -01
{X-NN  -08

I need to flag those where the number is not the same for all ID's.

If all values are +00, a simple

Code:
if string = translate(string, '000000000', '1234566789') then

works, but it (obviously) fails for cases where all values are the same, but not +00. One added complication is that the space following the number may in future be replaced by a space, or 'a', or 'b', or 'c', or 'd'.

This long-winded approach obviously works (and can be adapted if/when the a/b/c/d might be added at some stage):

Code:
ok = 1
do i = 2 by 2 to words(string) - 2 while ok
  ok = word(string, i) = word(string, i + 2)
end

I think your "obvious" approach looks pretty good.

If a loop cannot be avoided (as I suspect), better stick to the obvious.
