I seem to be having a conceptual problem with the "While" and

the result of the "While" is false that the enclosed applications
will get run. Is this expected? It seems to be counter-intuitive,
but I don't know what the intent of the While routines is. I could
of course put a "GotoIf" before the While loop to check to ensure
that the first expression is true before entry into the While loop,
but that seems redundant and ugly since the while point of While and
EndWhile is to avoid the inelegance of GotoIf, I thought.
If anyone can't come up with a better explanation, I'll open a ticket
on this but I'd like to first make sure that this behavior is not
expected.
exten => 2231,1,Set(staticnumber=0)
exten => 2231,n,Set(counter=1)
exten => 2231,n,While($["${counter}"<"${staticnumber}"])
Put A space around the < operator, like this
exten => 2231,n,While($["${counter}" < "${staticnumber}"])
This should help it.
That's no longer required in CVS-HEAD, if I recall correctly.
In any case, this does not make a difference, and even looking
logically at the example shows that it is not behaving correctly. (It
parses correctly on the second instance, but not on the first.)
This is looking more like a bug the longer I think about it.
