Assignment 1


Write an 8086 assembly language program which modifies the (15-byte) character string in bytes 600H to 60EH as follows:  all capital letters should be changed to the corresponding lower case letter;  all other characters should be left unchanged.

Write two versions of the program:  one version which uses indexing, and a second version which does not use indexing (it does instruction modification instead).  Be sure to include comments in your program, and in particular include a line with your name and which version this is.

This assignment is due on October 5th.  There is a penalty of 1/2 point (out of a total of 8 points) for each day late.

Email your assignment (the listing files produced by the Dewar assembler) to our e-tutor, Aldo Nunez, at ajn203@omicron.acf.nyu.edu.  Include your name and "Asgn 1" in the subject line.
