[SR-Users] Question about LCR

Hello,

AVPs are multi-value variables, so:

$avp(x) = 1;
$avp(x) = 2;

Create a list with two values, the last added is first retrieved. You can
use indexes to access them.

For example:
- $avp(x) will return now 2 (same as $(avp(x)[0]) )
- $(avp(x)[1]) will return 1

You can use variable as index:

$var(i) = 0;

then: $(avp(x)[$var(i)]))

To go through the list, you can use while(...) { ... } statement with an
variable for index that increments in each step.

When there is no value for avp at that index, then the returned value is
$null, e.g.,

while($(avp(x)[$var(i)]) != $null) {
   ...
   $var(i) = $var(i) + 1;
}

Cheers,
Daniel
