Try   set %1=%[%1];%2

Works for me.

Hi. What is the filename for this program?

I have uploaded to the SimTel Software Repository (available by anonymous
ftp from the primary mirror site OAK.Oakland.Edu and its mirrors):

pub/msdos/4dos/
tfc22.zip       Floppy cataloguer for 4DOS/NDOS users (+TPsrc)

Tobi’s Floppy Cataloguer and Catalog Viewer version 2.2 is specially
designed to work hand in hand with 4DOS.  It helps you to easily keep
a catalogue of all the floppy disks you are using to archive your
shareware collection. It uses the 4DOS File Descriptions to annotate
the files.

This package contains two programs:

  TFC.BTM – "Tobis Floppy Cataloger" a 4DOS BTM File
    ——————-Creates a catalogue file from your floppies

  TCV.EXE – "Tobis Catalogue Vision" a Turbo Vision Program
    ——————-Lets you view and search this Catalogue file

Together they enable you to easily maintain, view and search a Catalogue
of the floppies on which you are storing your programs.

Requirements:  4DOS 4.xx the ultimate command.com replacement.

Highlights:

  Automatically adds the 4DOS file Description to the Catalogue
  Adds 1 Line per Disk, stating Disksize and Free Space.
  Lets you view and search Your Catalogue on Screen with a SAA
         user interface based on Turbo Vision by Borland.
  It is free.
  All sources are included!

New in this release:

 V2.2: – Screenmodes bigger than standart 80×25 are possible. Just set
         your vga-card to a higher resolution, using the utilities you
         got along with your card, then start TCV.
       - TCV: the current serach-string.
       - TFC: can also be used to Erase Disks form the Database.
         Use ‘ TFC "games" ‘ to kill the "games" Disk from the Database.
       - TFC: Added Quit Option, when Scanning Disks without
         descriptions
       - TFC: Write Free Space on Floppy to the database entry.
       - TFC: Corrected Handling of 0 Size PROG.TFC
       - The source of TCV is included with the package.

Hi guys, I run a Ham BBS under DESQview 2.41 and have a batch file
run every 10mins to copy mail files.  The batch file is run using
4DOS v4.01 and when it completes, and EXIT command closes the DV window.
The file is run as a DESQview task using DVCRON to call the .DVP file.

Eventually, I got errors…the NS one from 4DOS which means that it’s
run out of shell numbers!  It would appear that the shell isn’t closing
properly and releasing the shell number.  I’ve checked this with the
PROMPT $z… command.

Also, I’ve included DVCleanup = Yes in the 4DOS.INI file and set the
appropiate swapping…EMS with EMS allocated in DESQview.

Query:  Does anyone else suffer from this problem?
        Would v4.02 cure it?
        I am exiting from the batch file in the correct way?

Thanks in advance….Andy, G8JFF

In todays computing env when any amount of processing power and resources
seem less (atleast to me), I am very "picky" about the behind the scene
programs/utilities that will be taxing the system all the time. 4DOS
seems to be an excellent product and I have read a lot about it (even IBM
uses it to attract people to its OS/2 2.1 :-)). But the question remains
about the overhead of running 4DOS. More specifically, how much more RAM
is taken by 4DOS as compared with COMMAND.COM and how slow/faster is it
as compared with COMMAND.COM. I have noticed that when I do a first time
DIR on a directory, there is a slight delay before 4DOS prints out the
directory listing while there seem to be no delay when doing DIR listing
with same switches under COMMAND.COM (/p /o /c). I would appreciate any
and all info on the topic.

Thanks very much.
Malik.

p.s. My system 386+387 DX/40, 8MB RAM, DOS 6.0 (DoubleSpace enabled).

I have a few more questions about the 4DOS that have to do with aliases.

1.How can I use the command "DEL /P" in an alias and still call alias the
  "DEL"? When I try "Alias del=del /p", it gives me alias loop error. Or
  I can use "Alias rm=del /p" but I don’t know how to disable the delete
  command when "DEL" is entered on command line.

2.How can I combine more than one command for an alias? Just like MS-DOS’s
  DosKey’s "$T" keyword that lets you assign a series of commands to an
  alias.

3.Is there anyway to access macros defined under MS-DOS’s DosKey while
  running 4DOS?

Thanks very much.

Malik.

Hello 4dos likers !
two ,three question for you all :
1) what is the benefit of the new Rev. of 4DOS ?
2) Can someone send me a zip+uudecoded file that contains some useful BTM
programs to run on my 4dos machine ?! (and to lern to write BTM)
3) Is there any way to compile BTM program like : BAT2COM but with the
fetures of the BTM ( memory "resident" runing ) !

Thanks for all the pointers. I finally got it to work. Here are my
solutions. I have checked, they work.

Help ! ! I have  upgraded to Dos 6.2 and everything works fine until….I
start PC-NFS 5.0 and Windows for Worgroups 3.1 and then shortly after
Windows is loaded the system hangs up. No mouse movement no nothing. I
can run packet drivers and Windows for Workgroups and everything seems
happy. The system is a 486-66 with all the bells and whistles.  I spoke
to Microsoft Tech centre and as far as they know everything should be ok.
I spoke to our Computer centre regarding a possible upgrade for PC-NFS
5.0 and Dos 6.2 and they never heard of such a thing.

I tried to redirect the output of Borlands grep program version 3.0
to a file named "p1.i".  I got an error message about sectors not
being found.  Disk doctor saw no problems with the hard drive even
after the long sector check.  The problem seemed to lie with p1.i
already existing in the directory.  4dos was willing to overwrite
say… "p1.inf", but not "p1.i".  I was not using a disk caching
software and command.com seemed to do this just fine.
