Hello,
I've got an algorithm that changes 1 byte int
to 2 byte char...
pre-condition: al := converting content
post-condition: ah == higher byte, al == lower byte

---- this is the code ----
pusha
mov ah,0x00
mov al,a
aam
or al,0x30
mov a,al
or ah,0x30
mov b,ah
popa
---- END ----

oh, a and b are just desired position in memory,
i did this with my c++ compiler and they just went
into the variable (char)a and (char)b.
