Returns information about currently set variables, local or set.

$var(variable name [,N])[.value|.local|.secs]

Variable name is a wild card value.
N tells us we want the Nth matching variable.
- N is 0 by default, and therefore can be used to check for existence without it
Returns
- Variable name by default
- Value if .value is specified
- If .local is specified, returns $true or $false based on whether or not the matching variable is a local variable

How to search through local variables only:

var %i = 1
while ($var(%varwildcard*,%i).local) {
  echo -ag $var(%varwildcard*,%i) is a local variable
  inc %i
}
