kty11,

I hate to be the bringer of bad news but it is not because your program didn't crash that it performed successfully!
a. The routines "show_ah" and "show_al" should call "show_al_high_4bit" first.
b. The instruction "call read_pusha_regs" does not deliver the correct register contents! Register DI will contain the returnaddress of the call!!!!
c. Do you think that segment registers can not be MOVed to the AX register?

I realize that these are your first steps in assembler. Please try to keep the complete source in 1 text file. At least while you are learning to program and are hoping to get meaningful feedback from others. (I gave up on your dotting program on account of this!)

Hi kty11,

Here you can find a similar attempt.

Display 16-bit registers

one thing I wonder: do I must keep source in 1 text file?

kty11, It is better to keep the source in one file, when you write it with learning purposes. You are very beginner and this should make the learning easier.
Also try to keep the source as simple as possible. Write detailed comments (for yourself). Edit the source, even if the program works and try to make it as readable as possible. Try to create more than one solution of the problem.

I always keep few sources in a directory for the project.
This is how my IDE works.
It is time proven to be effective.
