Can anyone help me how I can start with my program in assembly language? My task is to write a program that will ask a user for an input (just a single letter, number, or special character) and the program will determine whether the user's input is a letter, number, or special character. any thoughts? Please help! Not asking for the exact code here as I want to learn how to do it. Im planning to figure it out step by step but any help will be appreciated. By the way im on a windows x86(32bit), also I am doing this w/ a TASM. Thank you very much!


First, visit this page:

Click Here

Now you employ the 09h to invite the user to press a key.

You employ service 01h to read a character

You test what is the character and employ the 09h with the apropiate message.

Please, forgive me if I am wrong.
