SjASMPlus от z00m

[Ped7g]

it's modified to follow common compilers, output is STDOUT (you can assemble with machine code going to STDOUT), and errors/info is going to STDERR.

So to redirect the errors into log file use "sjasmplus file.asm 2> log.txt" (at least in linux/bash, not sure if this works in windows and in which shell, google how to capture STDERR in your shell, if the "2>" doesn't work).
