No. The compiler already uses &.
& means 'the following is an identifier even if it is a keyword'.
You can perfectly declare and compile:
Var
&if : integer;
begin
&if:=1;
end.
So &if is a bad idea.
Yes it is possible. Anyway it is better idea than IfThen. You treat facts
selectively. How often is used &if and how often is used IfThen?
You missed my point.
&IfThen looks also good (I like shorter syntax &if). With "&" prefix it is
obvious that this function is unique.
You misunderstand.
The & character cannot be used as part of an identifier, it is a special token.
It is eaten by the scanner. The parser will never see it.
You simply cannot define "&if' as an identifier. The parser will always see 'if'.
scanner.pas around line 4607.
And modifying the scanner for this exception is a REALLY bad idea.
Michael.
