Hello,

No matter what I do, when I try to create an executable out of a 2 line script in DBC, it turns it into a 1.5 megabyte executable. I'm using Build Executable and not Build Final.

What gives?

Enjoy your day.

It may have something to do with the fact that it includes the entire 3d engine into the EXE even if you don't use it. I think a man named The Winch created something to make them smaller?

When compiling a DBC program, a runtime version of the language is merged and saved
with the compiled code. Essentially the entire command set is contained
within the executable. DBC doesn't compile to machine code which means that
it gets enterpreted during execution.

Ack!!! You answered just before me. Oh, well...

It does, but that 1.5MB packs down nicely. Even a standard zip will take it to the 600KB mark. DBC isn't totally alone in this either, you'll find similar results from languages like Blitz or Torque. Pure Basic is the only really superb 'tiny EXE' language I've seen in a long time (beyond C++ that is), but if you start doing any 3D in that you get the whole Ogre libs packed into the EXE, and suddenly it jumps up in size again.

I guess I got surprized because I've seen smaller executables of DBC. I'm guessing they were created in an earlier version and therefore didn't have the same number of commands or functions.

Enjoy your day.

The DBC EXEs haven't changed all that much really. The EXE could well have been packed with the likes of UPX.
