$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)
