A student writes: Dear Professor Patt, Would it be acceptable to you if instead of storing the 16 input values into 16 new locations different from the output I stored my 16 values directly into the final output locations starting at x4000 and arranged them from there? Thanks, <<name withheld to protect the student with an excellent alternative to .BLKW> Apparently, the .BLKW pseudo-op is still confusing to many students. My guess is that in a few weeks you will wonder why you ever were confused by it. But right now, you have a program to write. Since this student found a simple way to handle the problem (do not change the contents of x3200 to x320F) without using the .BLKW, I thought I would share it with you. It is very much okay to copy the grades over to x4000 to x400F and start sorting from there. If you do end up clobbering the original input data in x3200-x320F, it will not severely impact your grade on the programming lab. Good luck finishing the program on time. Yale Patt
