Hi,<br/>Can anyone please help in converting the ASCII code to BCD using the assembly language. I am new to this language and have no idea where and how to start.<br/>help will be appreciated<br/>thanks in advance.

I wanted to introduce myself.I currently program in assembly using masm for 32 bit apps. I used to write in C and C++ but decided I didn't care for the code bloat. It is harder in assembly, but the speed and size are worth it to me.I do still write and maintain 16 bit code as well. Most of it s...
