I've recently started to learn fasm and i must say I like it, just have a two questions for you:

How do i get the command line parameters? Searched the forums and found something when using com executables, but can't figure it out when using "format PE console".

The last question is about the program's return code. Does it return the content of eax to the system when doing the 'ret' command?

Thanks in advance.

Welcome snifit, some answers to your questions:
For PE consoles, you can use GetCommandLine api, then eax points to full command line.
For PE programs, the returned code is the argument given to ExitProcess call.

AFAIK, GetCommandLine API function works for GUI PE applications as well.

Of course some parsing of the command line, obtined this way have to be provided.
There are several procedures for this task, discussed on the forum.

Regards.
