Hello, I recently came across a neat little program that I would like to share called "Batchcom". Batchcom is a converter for batch files that turns average to complicated batch files into COM files. The folder also has a com2exe converter as well. It also had a COM compressor, but I couldn't get it to compress anything. Oh and also, it supports it's own syntax like frames and windows.

This one has been rotting on my disk for the past decade or so.

why would i want to convert batch to com/exe?

I use batch for compiling and testing, it would be painfull to do that from exe.

Why? It's the same thing as a batch file, but it runs natively and faster.

Run a batch file, at least you can see what the commands are.
Run an exe and you take a chance...

I also can't see how you would notice any sort of speed difference nowadays. Maybe in the days of DOS3 running from a floppy?

hello.bat=30 bytes, hello.exe=1243. Bloat? Smile

That's true; however, in the long run, when batch file get up into the 40k-80k area, converting into a executable is far better. Also why would you want people to see what commands are being run if you're releasing a commercial program?
EDIT: Just compiled and compressed the OpenGEM startup batch file. Old size = 4578 New size = 3270.

40KB batch file? Wow, what a pig to maintain. I would be splitting it into smaller batch files and using call.

Using hello.bat as an example was a bit extreme, the more commands in a batch file the more efficient a compiled exe would be.

Did that startup batch file have lots of blank lines and/or comments?
Quite a few batch files are 'bloated' with that stuff.

about 4 or so blank lines and maybe 8 rem, but only 7-10 words. Less than a kilobyte.

Commercial? With this? Are you fucking kidding me?

batch isnt for long run. its to replace something like this:
Code:
@echo off
:a
type conin$ > nul
fasm x86\main.asm boot.img
if %errorlevel% neq 0 goto a
"%ProgramFiles(x86)%\Bochs-2.4.5\bochs" -f "bochsrc.bxrc" -q
goto a    


I dont thnik its a big deal to do bat to exe.
All you need is CreateProcess, WriteFile, GetLastError, CreatePipe and compare operator. I odnt know batch that well, but i dont think it has some complicated syntax. Just creating processes, loop and if.
