ParameterTypeDescription
varNameStringName of a process or interprocess variable
Function resultPointerPointer 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}" to Get pointer. However, you cannot use 2D array elements (ArrName+"{3}{5}") or variable elements (ArrName+"{myVar}").

Example

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
