Students now-a-days face difficulty to learn assembly programming , as the windows 7, 8.1 and 10 64bit versions are out.
i used dosbox to help run these apps on 64-bit environment without any flaws. Its just a social work to help students learn.
MASM 6.15 with debug and dos 6.22
Hope u learn something!
