该博客介绍了两种在汇编语言中实现数值转换和打印的方法：打表法和直接法。通过示例代码展示了如何将16进制数转换为ASCII字符并输出到屏幕上，详细解释了每一步操作的含义和作用，涉及数据段、栈段和代码段的设置以及中断调用。

打表法：

DATAS SEGMENT  
    array db 01H,25H,38H,62H,8DH,9AH,0BAH,0CEH
    ascii db 30h,31h,32h,33h,34h,35h,36h,37h
          db 38h,39h,41h,42h,43h,44h,45h,46h
    n dw 8
    x dw 0
    y db 0
DATAS ENDS

STACKS SEGMENT

CODES SEGMENT
    ASSUME CS:CODES,DS:DATAS,SS:STACKS
START:
    MOV AX,DATAS
    MOV DS,AX
    
    mov cx,n

    mov bx,x
    
    mov dl,array[bx]
    inc bx
    mov x,bx
    call output
    mov cx,n
    cmp cx,1

    mov dl,','
    mov ah,2

    mov y,dl

直接法：
