This compiler error will occur if you try to use a keyword as variable name.

For example:

var 
    nOT // this is the not keyword !!!
begin

Usually, as is the case above, the syntax highlighting of the macro editor will turn the variable to bold if it corresponds to a keyword. This should be an immediate clue (even before compiling) that the variable name is not allowed.
