    Question ERROR:Operator not applicable to this operand type, help

    hello, me agian Bubblez101

    I got an error that i never seen before. knowing what it actually means would be a great help.

    This is the error:
    Operator not applicable to this operand type

    here is the code that the error highlighted on:

    if not ch := LetterList then
    showmessage('You have used that letter already, choose another letter!');
    LetterList.add := ch+LetterList;

    I have declared this after implementation:

    var Letter : array[1..26] of char;
    LetterList = record
    Letter : char;

    Thanx in advance for any help. Agian.

    "ch := LetterList" is a statement. It has no return value, so no operators can be applied to it. You are trying to use "NOT". This looks like you have some C or Java background... Delphi / Pascal doesn't support the C-Way of assignments where you get the assigned value as return value.

    ch := LetterList;
    if NOT (ch<>0) err, nonsense: if ch=0 then...

    (the NOT operator in Delphi can only be applied to boolean expressions)
