How to Read a Character String With Assembly Language

The 8086 Assembly Language is a programming language used by developers who need to create core-level applications for microprocessors. Unlike other languages, Assembly can only manage a single character string at a time. If you want to access the value of the current character string, you can do so by adding specific instructions to the source code.

Instructions

1. Load the source code of the application in your Assembly Language editor. If you do not use such an editor, load the code in Notepad.

2. Type the following instructions at the point where you wish to read the string:
   int 21h
   ret

   While "int 21h" returns the value of the default character string, "ret" prints it on the device or computer's screen.

3. Open the "File" menu and click on "Save."
