As Chuck said, replying to you is a bit iffy, so I'll post (apologies to
those who couldn't care less).

First, make sure that you have your system set up properly for Draco. You
should have the following assigns

    DRINC: the include files (the 1.2 ones are best)
    DRLIB: the Draco libraries and startup code (if you are using the
	1.2 compiler, you must use the 1.2 libraries and startup)

Then, you should also have the various link scripts in your S: directory.
These are the things like drraw, dr1, dr1lib, dr2, etc. If you are using
AmigaDOS V1.3, just set the script bit on them and use them as commands.
Thus, if you are linking just a single source file which uses the I/O
constructs, you would link with

    dr1 myfile

What this would effectively expand to is:

    blink from drlib:drstart.o+myfile.r
	library drlib:drio.lib+drlib:draco.lib+drlib:exec.lib+drlib:dos.lib
	smallcode
	to myfile

From your message, I would gess that you are doing your linking manually
with BLink, and are missing something out. If you are using any of the
Amiga libraries (e.g. intuition.library, graphics.library), then you must
add the appropriate library from DRLIB: to the above list (as in
"drlib:intuition.lib"). If you want, you could just JOIN all of the
libraries (NOT the startup files) into one huge "amiga.lib", but that
slows down the linking.

P.S. I now have a Draco V1.3 (beta), which cleans up the code a bit more in
some places, and adds symbolic information for file-level variables. This
latter is useful in my symbolic disassembler (to be released soon - problems
with my CDC disk drive are slowing me down), and a future debugger.
