There are two ways you can define a pointer to a variable:

1. You can use the command Get pointer, which returns a pointer to the variable.

C_POINTER(vPointer)
C_TEXT(Variable1)
Variable1:="Hello"
vPointer:=Get pointer("Variable1")

2. You can also define a pointer to a variable by using a predefined pointer symbol (->).

C_POINTER(vPointer)
C_TEXT(Variable1)
Variable1:="Hello"
vPointer:=->Variable1
