You should define macro before you use it. "display kk" is here
interpreted as a built-in "display" directive, which needs bytes or
string as an arguments, and the kk is larger than byte (because it's
above 100h due to the "org" directive) that's why you've got
"value out of range" error. If the kk was less than 100h, you'd have
simply this byte displayed at compile time and no code generated
before "mov ah,4ch".
  To do what you wanted, simply move the macro definition to
the beginning of your source.
  This happens only with preprocessor symbols (macros and equ's),
labels and constants can be accessed from anywhere.
