A82: Re: Displaying # value in 'a' = use ROM_CALL(M_CHARPUT)??
This will show char number 3 in the menu font. To display the char '3' add
'0' to the number before you show it (this only works if 0<=(level)<10).
If you level can get bigger than 9, but not bigger than 99, convert it to
BCD and show one char at a time. Otherwise I would D_HL_DECI or UNPACK_HL
to show the number. If 0<=(level)<100 then you might want to store the
number as BCD (actually packed BCD), so you do not need to convert it
(remember to use the DAA instruction).
