Flags
Flags are one-bit operands. This means they can either have the value TRUE
or FALSE.

Global variables which are assigned to permanent addresses (%MX)

Non-volatile
 Quantity: 256
 Flag numbers: 0 ... 255

Global variables which are assigned to permanent addresses (%MX)

Non-volatile
 Overlaid by registers 1000000 through 1000055
 Quantity: 1,792

Flag numbers: 256 ... 2047

Global variables which are assigned to permanent addresses (%MX)

When the operating system is launched, special flags are initialized using
their default values.

In the program listed below, a flag is set when the user presses key F1. If key
F2 is pressed, the flag is reset. As long as this flag is set, special register
362100 (Status LED) is incremented. Incrementing of the special register
continues until the flag is reset.
Var
Merker1: Bool At %MX 1 ;
Input_Button_1: Bit At %XL 361000.0 ;
Input_Button_2: Bit At %XL 361000.1 ;
Status_LEDs: Int At %VL 362100 ;
End_Var ;
Task Main Autorun

Loop
If Input_Button_1 Then
Merker1 := True ;
ElseIf Input_Button_2 Then
Merker1 := False ;
