Get pointer

Get pointer ( varName ) : Pointer

Parameter	Type		Description
varName	Text	→	Name of a process or interprocess variable
Function result	Pointer	←	Pointer to process or interprocess variable

Description

The Get pointer command returns a pointer to the process or interprocess variable whose name you pass in varName.

To get a pointer to a field, use Field. To get a pointer to a table, use Table.

Note: You can pass expressions such as, for example, ArrName+"{3}", as well as 2D array elements (ArrName+"{3}{5}") to Get pointer.
However, you cannot pass variable elements (ArrName+"{myVar}").

Example 1

In a form, you build a 5 x 10 grid of enterable variables named v1, v2... v50. To initialize all of these variables, you write:

  // ...
 For($vlVar;1;50)
    $vpVar:=Get pointer("v"+String($vlVar))
    $vpVar->:=""
 End for

Example 2

Using pointers to elements of two-dimensional arrays:

 $pt:=Get pointer("a{1}{2}")
  //$pt=->a{1}{2}
 $pt2:=Get pointer("atCities"+"{2}{6}")
  //$pt2=->atCities{2}{6}
