When compiling this program section, the exit command in fortran did not produce the correct token

    do
        print *, "Add:"
        read *, a
        if (a == 0) then
            exit
        else
            sum = sum + a
        end if
    end do

[@63,392:395='exit',<NAME>,16:12] was produced from the -tokens output
[@63,392:395='exit',<EXIT>,16:12] is the expected token

This was because the NAME lexer rule came before the EXIT rule, taking precedence. I reordered them in the lexer, which fixed the issue.
