An identifer is a symbol used in a Pascal program which consists of letters, numbers and certain special characters, used to indicate a specific variable, constant, object, record, type, procedure or function.
For example, in the following piece of code:
program WittsEnd;
const
Y=2;
var
Plugh: Integer;
procedure Xyzzy;
begin
end;
begin
Plugh := Y*2;
end.we can say that
- WittsEnd
- Y
- Plugh
- Xyzzy
Are all identifiers.
