Question

Assembly Language using Irvine 32 library, Must be assembly, not c/c++/java

Ask the user for a string input and then use that string to create a text based screensaver. The text should start in the upper left corner and move towards the right. When the string gets to the end of the screen, it should move back to the left side but moved down one line. This should repeat until the text hits the bottom of the screen at which point it returns to the top of the screen and repeats its previous actions(moving to the right and then down one line once reaching the end of the screen). The speed is up to you. The program continues until a key is pressed. Use macros from the Macros.inc library
