[Y_Less]

This problem stems from a little known feature of the compiler relating to line continuations:

pawn Код:

#define A \
    27

That is a valid define because the "\" means "continued on next line". In your code you end the comment with "\\", which tries to tell the compiler to continue the comment on the next line, but you can't do that with comments, hence the first error. The second is likely just a result of the first error (whenever you get a lot of errors ALWAYS fix the first one and try recompile - it's often the case that the others are caused by the first). Also, this is covered in pawn-lang.pdf had you bothered to look there.
