Even with the HLL-like procedure call, you still have to learn the call instruction to use HLA properly. There are things like "call( eax );" for which there are no HLL-like equivalents. hLater, Randy Hyde

As you may have recognised by all the answers got so far, we wont do your homework (and I've seen this your question already). But if you really want help from this group, tell us what you not understood and/or where you got stuck. __ wolfgang

Does the > instructor know there's no FPU on an 8086??? The question did claim it was single precision real. And they *did* have 8087s back then. But even if you didn't have an 8087, there's nothing stopping you from writing your own floating-point routines in software. Maybe the instructor doesn't know the difference between 8086 and 80x86. Maybe the student didn't copy the assignment across properly. In any case, computing the log of 100.5 is no more difficult than computing the log of 0.1. Other than cheating, you're still going to need some function (or instruction) to compute the value for you (unless the class is full of brilliant numerical analysts and the students are expected to write this code on their own -- probably not given the level of the other assignments). I'd guess that this student didn't exactly tell us everything about this assignment. hLater, Randy Hyde

There are things like > "call( eax );" for which there are no HLL-like equivalents. Okay... so you're saying there *have* been questions like this, and I;ve missed 'em (or my memory's bad). Quite possible. I see a few instances - damn few - of "call" in the "examples" directory... If I were to ask on the !Yahoo! group, "how many of you know the call instruction?", how many answers do you predict I'd get? (careful, it's an easy experiment to conduct! :) (yeah, I know I just asked "how many of you are using Linux?"... apparently zero, which I don't think is the correct answer) Best, Frank
