I did a bit of searching: you should be able to find a copy by typing "helppc abandonware" in Google. Let me know how it turns out, okay?
I have downloaded HelpPC 2.10 and in fact I remember using this very useful tool in the early 90s. Good memories
Well, if I didn't get it wrong and according 8086 timings here it is:
lOOP takes 18 clocks when jumps and 5 clocks when no jumps. Bytes size is 2.
DEC takes 2 clocks and Bytes size is 1.
JNZ takes 16 clocks when jumps and 4 clocks when no jumps. Bytes size is 2.
So, DEC+JNZ takes 18 clocks when jump and 6 clocks when no jump and Bytes size is 3.
But according to the Cheat Sheet
provided by chibi lOOP takes only 17 clocks when jumps and 5 clocks when no jumps.
It seems it's better to use LOOP instead DEC+JNZ. What do you think?
