Well there is really no way I can get the scource of this program. It was
written before my time without proper version management and I only have got
the newest scource and there is unfortunately no possibility to get the one
I need... That's why I was looking for some kind of workaround but of course
recompiling freecom was not the answer I was hoping for :). Anyway thanks
for the helpful resources, I'll take a look!

Thanks for your concern but it's only dispensable data and the automatic
call through the program should not cause errors but you'll never know.
Actually I found an additional protection in deltree which spoils unintended
deletion of data from root directory. However as "alias" is only working in
prompt it won't matter I guess (or maybe it will if I am going for the
freecom compile...)

Is this program something you wrote or somebody else? Is it closed
source? Because this is really sounding like some extreme (i.e. not
recommended) workarounds for a flawed design.

You can recompile FreeCOM, but I wouldn't recommend it. I'd suggest
you fix your program (if at all possible). Of course, that may not be
feasible.

The sources on SourceForge for FreeCOM are for old stable 0.82pl3,
which (AFAIK) needs TurboC (or maybe TC++), but I don't know if that
includes Suppl or not. (I haven't tried lately, plus there is no
active maintainer.)

* http://edn.embarcadero.com/article/21751  (Turbo C++ 1.01)

I don't see any 0.84pre2 sources on iBiblio in the obvious place
(pointed to by read-only Software List, in "BASE"), but I think I can
find it elsewhere.

This one (I assume) already has Suppl inside, but here it is anyways
(just in case):

Jeremy once said that the SVN version of FreeCOM compiles with
OpenWatcom and works fine, but I haven't tested it myself.
Nevertheless, here it is, if you really want to recompile:

Nevermind my answer. This may work directly from prompt but not from within my 
program. I guess I need to do it in command.com. So can you recommend any good 
documentation on how to compile freecom and maybe which source?

del C:\directory\*.*

rd C:\directory

 

Even that will fail, I think, if there are some hidden files/folders.  Start 
with that and you can build it into an alias command in freecom.

 

alias myrd="del %1%\*.* ; rd %1%"

 

I believe that's the right syntax.

Hey all!

 

Once again I am trying to run some old programs under Linux emulation DOSEMU 
which is making use of FREEDOS. In one of them you have the option to delete 
directories, it does it like this:

del C:\directory\*.rec

del C:\directory\*.dat

del C:\directory\eti.bin

rd C:\directory

 

As “rd” only removes directories if they are empty the folder to be removed 
must only contain files of types .rec, .dat and a file eti.bin else it won’t be 
removed. My problem is that today there are some other files in this folder too 
so I can’t remove it from within my program.

The appropriate way to delete directories would be ‘deltree’ I guess but that’s 
a standalone .com program while rd and del are part of command.com 
<http://command.com> . I tried to create a file rd.bat which should catch the 
call but if I do “rd.bat” freedos wants to remove the directory “.bat”. Is 
there any way to get a workaround to this or how can I compile my own version 
of command.com <http://command.com> ?

 

Thanks

Hans-Christian
