Get pointer



	Get pointer ( varName ) -> Function result

Description

The Get pointer command has been rewritten to support new pointer types in 4D v15 (see the Unicode mode for methods section). The following modifications need to be taken into account:

Pointers to two-dimensional arrays, including using expressions, are now supported:
$pt:=Get pointer("a{1}{2}") //$pt=->a{1}{2} $pt2:=Get pointer("atCities"+"{2}{6}") //$pt2=->atCities{}{6}

Invalid names for variables now produce an error 77 ("Bad variable name"). In previous releases, they were accepted. For example:

$pt:=Get pointer("123") //accepted in 4D < v15 // rejected in 4D v15 and later versions

Extraneous white spaces are now supported:
$pt:=Get pointer(" a ") //accepted in 4D v15: "->a" // rejected in 4D < v15
