How can I get a name for a temporary file in a .bat file?

OK, I'll bite.
Can you elaborate a bit? Give some more detail about what you
want to do?
What do you mean by 'get'?
What is a 'temporary file'?

In other words, is the temp file created by some program or are you trying
to generate a random filename to use for your own temp files?

Oh, Todd, you have such a way with words!

In WSH (Windows Script Host), the GetTempName method
is provided for exactly this purpose. For example, the following
line of VBS code will display the result of GetTempName:
WScript.Echo CreateObject("Scripting.FileSystemObject").GetTempName
However, to run this command and retrieve the result in a variable
itself needs a workfile (containing the VBS code), which begs the
question.
As an alternative approach, which doesn't require a workfile,
is to use the RANDOM variable to generate a workfile name.
The following code shows how to create a temporary workfile
name of format WRKnnnnn.TMP that doesn't conflict with any
existing file, and loads it into the variable WorkFile:
Lines that aren't prefixed with two spaces have wrapped in transmission
====Begin cut-and-paste (omit this line)
@ECHO OFF
SETLOCAL
:LOOP
SET /a WorkFile=%RANDOM%+100000
SET WorkFile=WRK%WorkFile:~-5%.TMP
IF EXIST %WorkFile% GOTO LOOP
ECHO. Your temporary workfile name is %WorkFile%
====End cut-and-paste (omit this line)

Sorry. First thing that came to mind was, either we would see a textbook
response to your final question, or an extremely long response unrelated to
the actual task. Oh well.

Assuming that this is what the OP is asking for, then how about this?
==========begin file C:\cmd\demo\GetTempFile.cmd ==========
01. @echo off
02. setlocal
03. set tempfile=%date:~4%%time::=%
04. set tempfile=%tempfile:/=%
05. set tempfile=%tempfile:.=%
06. set tempfile
==========end file C:\cmd\demo\GetTempFile.cmd ==========

Hey, don't apologize! You hit the nail on the HEAD!
I'm kinda disappointed, 'cause I was also curious about what kind of
response we would get...
