3.7 General screen form variables

Registers are needed to be able to exchange data between different screen forms.

Registers are assigned to a screen form. They are loaded when the first screen

form is generated and assigned the value 0 or a blank string.

x Number of register with x = 0...19

Real or String type = Variant

Registers with x ≥ 20 are used by Siemens.

Registers may not be used directly in OUTPUT blocks for generating NC code.

The assignment of values to registers is configured in a method.

Identifier.val = Register value

Identifier = Register value

REG[0] = VAR1

REG[9].VAL = 84

These registers can then be assigned to local variables again in the next screen
