Toggle( x ) applies to byte, bits and bitfields. Other structures including boolean are prohibited. I would like to see toggle( boolean ) implemented. I would be happy for it to be identical to toggle(byte).

I wrote a

procedure toggleb(b: Boolean);
begin
if b then
b:=false;
else
b:=true;
endif;
end;

to do just that

b := b XOR $FF

Hi Gunter.

I wasn't meaning to ask to toggle byte - I thought that was already there (I misread the manual).

Often I have something like

Code

var
MyVar[@MyByte, 3] : bit

and then in several places

Code

Toggle(MyVar);

I had occasion to redefine my bits as boolean by redefining MyVar as

Code

var
MyVar : boolean

For the most part that was all I needed to do, because largely bit and boolean are treated the same, but

Code

Toggle(MyVar);

was not valid. Hence my request.

Hello Merlin
a BIT is handled more as a Funktion than a simple VAR. This makes it impossible for using the toggle Funktion.

Hello Rolf.

Sorry, I don't understand. I use toggle with bits all the time.

E.g. from actual code:

Code

var
External_Watchdog [ @PortG, 4 ] : bit;

...

Toggle( External_Watchdog );

Ahhh... you mean the BIT( var, n) function. No I did not mean that.

Hi Rolf,

ich hab grad eben

Code

    If DispInvDo=true
      then
        DispInvDo:=false;
        Toggle(DispInv);
        SetMode(DispInv);
      EndIf;

getestet und es funktioniert nicht.

So geht es aber:

Code

    If DispInvDo=true
      then
        DispInvDo:=false;
        If DispInv=true
          then
            DispInv:=false;
          else
            DispInv:=true;
          EndIf;
        SetMode(DispInv);
      EndIf;

Mit deinem, wie oben geschrieben

Code

DispInv:=not DispInv;

funktioniert es auch.
