Assembly Programming Test

I whizzed past the assembler, add count in octal, subtract hexadecimal. Found error in the dump file, all zeroes and wondered, is this an omen? Surprise! write me an algorithm for a full third of test score. Sort all data in a file swap and exchange, compare and relate. Loop through the right number and oh, woe for me, I get a C plus. The highest in the class, all doomed to retake the section except me, who passes. But the A and B slip away because I never set my counters, important counters full of junk all back to zero. Zero the clean state of all beginnings. Programmers learn by trial and error, one pass, one dump and oh, yeah, zero out the counters Or face certain demise.
