Returns information about currently set variables, local or set.

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