The type BYTE in TDI Modula-2 (and most other modulas that have this
type) is identical in all respects to the type WORD save one: it is only
one byte instead of two (or four on some machines).  If the example had
been

VAR
  i: WORD;
BEGIN
  i := 90H;

then the problem might be more obvious to you:  type WORD (and type
BYTE) are NOT assignment compatible with ANYTHING that is not also
of type WORD (or BYTE).

If you want to get your code past the compiler, try:

  i := BYTE(90H);

Hope this helps.
