Toggle-field-dependent displays
The toggle field is overlaid with alternating graphics: If the value of the flag byte is 1,
"image1.bmp" will appear. If it is 2, "image2.bmp" will appear.
DEF VAR1=(IDB/*1="\\image1.bmp",
2="\\image2.bmp"//,$85000/wr1//"MB[0]"//160,40,50,50)
The size and position of the image is defined under "Position of input/output field (left, top,
width, height)".
2.3.5 Detailed information about the default setting [3]
Overview
A variable can assume various states depending on whether a default value, or a system or
user variable, or both, has been assigned to the variable field (I/O field or toggle field). (Not
calculated: Toggling is not possible until a valid value is assigned to the variable).
