I want to rewrite my loader in c and I want to give this compiler a try, 
but it is possible to compile to a binary file (like .com) with a start

I tried it and I need some more info.

I want to link several .obj files to 1 .com like file. What commands 
have I to give to the linker?

The next problems are the standard libs. I turn they of with the -NL 
switch, but when I want to link I get the errors, with a symbol 
__acrtused and with my function which is written and compiled with nasm.

The linker doesn't need any special commands. Generating .com files is the
"t" memory model. To create hello.com,

    dmc -mt hello

which will show how it is obj2asm'd and exe2bin'd.
