Delphi Compiler Error
E2038 Illegal character in input file – ‘%s’ (%s)
Reason for the Error & Solution
The compiler found a character that is illegal in Delphi programs.
This error message is caused most often by errors with string constants or comments.
program Produce;
begin
Writeln("Hello world!"); (*<-- Error messages here*)
end.
Here a programmer fell back to C++ habits and quoted a string with double quotes.
program Solve;
begin
Writeln('Hello world!'); (*Need single quotes in Delphi*)
end.
The solution is to use single quotes. In general, you need to delete the illegal character.
