I'm trying to figure out why in the below code, the PSTN_NUM variable is

"0010123456789") in new stack
It should evaluate PSTN_NUM and add a 001 only if: PSTN_NUM is 10 digits
long and doesn't start with a 0.
However, from the debug it's being changed, even though the first test
operator logically is 0. If seems as though the "&" isnt being applied.
Any ideas?
Thanks

hello,
you should try this:
exten => s,n,ExecIf($[ $[ "${PSTN_NUM:0:1}" != "0" ] & $[
${LEN(${PSTN_NUM})} = 10 ]]|Set|PSTN_NUM=001${PSTN_NUM})
cause the AND Operator is another thing to work, so the result at your
way look like this ExecIf(1&1 | ...) and with my way it looks like this
ExecIf($[1&1]|...) which is the right syntax for it.
best regards

Hi Steve,
I can see what yours does, but I still get the same end result (even
though theres only a single "0" result now)
:
exten => s,n,ExecIf( $[ $[ "${PSTN_NUM:0:1}" != "0" ] & $[
${LEN(${PSTN_NUM})} = 10 ] ] |Set|PSTN_NUM=001${PSTN_NUM})
-- Executing [s at macro-setpstncli:8] NoOp("SIP/427-b7d9a9a0",
"0123456789") in new stack
-- Executing [s at macro-setpstncli:9] ExecIf("SIP/427-b7d9a9a0", " 0
|Set|PSTN_NUM=0010123456789") in new stack
-- Executing [s at macro-setpstncli:10] NoOp("SIP/427-b7d9a9a0",
"0010123456789") in new stack
---------------------------------

There's an extra space between the opening "(" and the opening "$[", so
the result is space-zero, which is not the same thing as zero. Any string
that is not exactly "0" (or the empty string), such as "foo", " ", or " 0" is
true.

I did wonder where the extra spaces were coming from, but I thought that
was where the quotes were supposed to come into play... Well that got
it working so thanks guys.. |

The quotes generally aren't supposed to take care of spaces; they are
generally used so that variables which are unset do not create an invalid
expression, i.e. $["" != "foo"] is valid, but $[ != foo] is not.
