Assembly code with tons of segment

[lucky6969b]

My program does compile but does not link. ~100 segments
Do I separate each segment into modules?
Or the linker virtually doesn't allow that many?

Question 2:
if this program is a driver, And I downloaded winasm515 as a debugger IDE, I wonder if my app calls this driver, would the debugger automatically switch to the driver when necessary? I still don't have the program linked, so I am not sure.
Thanks

I would only expect such an excessive segment count if the program already is made up out of a vast lot of modules (i.e. compilation units). But in a scenario lke that, all those segments would most likely be part of a few groups that then would be contracted to an equal number of actual segments in the link stage.

However, if you really have around 100 entirely distinct and ungrouped segments I wouldn't be surprised at all when your linker throws up...

Why "if"? Didn't you say it's your program? In this case I would suppose you to know. I don't know the package you're using but the debugger actually may not allow you to step into code below ring 3 which actually could be a problem in case you want to debug a device driver. At any rate, I think you'll never know until you either try or thoroughly read the documentation of your assembler/IDE/debugger package.

he he why i said "if" was because it was a disassembly of "something" Blush!

Ah, I see. You must know that, although perhaps syntactically suitable for that, the output of a disassembler may not always be simply recompiled. Your "something" seems to be a bit unusual and/or complex to have the disassembler generate such a crude output.
