$get

Usage: $get(name)

Category: text

Description:

Returns the variable name (equivalent to %name%) or an empty string if name has not been set. If name is another variable (e.g. %indirect%) the value of the variable will be used as name. This allows the retrieval of dynamically named variables.

Example:

The following statements will return the values indicated:

$set(foo,This is foo)
$set(bar,foo)
$get(foo)              ==>  "This is foo"
$get(bar)              ==>  "foo"
$get(%bar%)            ==>  "This is foo"
$get(baz)              ==>  "" ('baz' has not been set to a value)
