Hello,
Using MS-DOS 7.1. Testing indicates that DOS detects
upper and lower case, and will preserve case during copy and xcopy
operations. Is it possible to change upper case to lower case using
DOS. Can it be done in a batch? I am aware of the fact that 4dos is
capable of this, but I do not want to buy 4dos. Timo Saldi? Do you
know how this can be done? <grin>

Best Regards,

I haven't answered up to now because I don't run Win95 so I can't test
the approach I have in mind. But, since noone else seems to have an
idea I thought I'ld tell you what I know.

I have played with the DIR /L switch a little in the past and know it
can be used to give you a lowercase version of a file's name. What I
don't know is whether you can actually affect the FAT's version of the
file name. However, if COPY and XCOPY preserve the file name's case,
then it may be possible. As I said, I just can't test it.

Below is a batch file that will convert a file name from upper to lower
case. I have tested it in DOS 6.2. You're on your own as far as making
do what you want.
:: LOWER.BAT - A routine that converts a file name to lowercase.
:: Tom Lavedas <k...@deltaelectronics.com>
::
@echo %dbgl% off
%2 if [%1]==[] %0 *.*
%2 for %%v in (%1) do call %0 %%v ::
%2 for %%v in (del goto:End) do %%v ente?.bat
> enter.bat echo ECHO REN %1 "%%4"
> ente}.bat dir %1 /l /b
>>ente}.bat echo.
> ente}.bat date < ente}.bat | find "Ent"
ente}
:End

The routine takes an optional filename argument (which may or may not
need to be capitalized). The filename can have wildcard characters.

You will need to modify the capitalized part of the eighth line to match
your requirements. It may be that this may be as simple as removing the
capped ECHO to activate the REN statement. As it is it simply echos
'REN FILENAME "filename"' to the console. I enclosed the lowercase
filename in quotes in the hope that it will force Win95 to take the file
name literally (not capitalize it).

Let me know how it works out.

You can do that (and much more) with XSET

Hello,
Thanks for this info, but this problem was solved by Tom
Lavedas with the following batch. The command syntax for using this
batch on a single file is:
lower filename.ext
and will use wildcards, as well.

:: LOWER.BAT - A routine that converts a file name to lowercase.
:: Tom Lavedas <k...@deltaelectronics.com>
::
@echo %dbgl% off
%2 if [%1]==[] %0 *.*
%2 for %%v in (%1) do call %0 %%v ::
%2 for %%v in (del goto:End) do %%v ente?.bat

> enter.bat echo REN %1 "%%4"

> ente}.bat dir %1 /l /b
>>ente}.bat echo.
> ente}.bat date < ente}.bat | find "Ent"
ente}
:End

generally,
conversion of text files to another case
is easily done using tr or sed
