Hello currently i am trying to write a program to take in user input and convert this input to ASCII or Hex depending on what they specify.The ASCII set in question is standard one from 0 to 127. I am wondering should i have a 2-dim array of ASCII chars and there hex equivalent. the difficulty i am finding is with special chars in the ASCII set,e.g Delete 7F.Say for example the user presses carriage return when prompted to enter the string for conversion.should i say enter string and press '999' to end as carriage return cannot be used.I am getting very stressed out with this programming problem. i am a hard worker but just cant seem to get over this problem. Hope the legends out there can help.
thank you very much
 
Using a 2dim array is not worth it. Strings ARE in ASCII, so if you have the ascii code as an integer somewhere, you just print it directly to screen, which outputs it as an ascii character. For instance, if al=65, you output an 'A.'

Your problem is much easier if you were to go directly to BIOS or hardware, but that may be more complex than you can handle. If you need to display 8, 9, 10, 13, you need to write them directly to screen. Entering these codes is another problem too.
