Hello !!

I need a program to check wether a certain data-path exists or not.

Here's my problem :
The user have to give in where he want's his data to be stored when
starting up a given program from Dos.

Normally he would start the program like this:

C:\>f:\wp\wp/ps=a:\wpdata

but I would like to put it in a BAT file instead.
The BAT file could look like this:

----------------------------------------------------------------------------
@echo off
:again
cls
echo 
echo Your data-path please ! (fx. a:, a:\, c:\wpdata, z:\data).
answer Data-path :    ** answer places the data-path in an environment
                      ** variable called answer.
XX                    ** XX indicates the program that I need to confirm
                      ** wether answer exists or not. The program have to
                      ** set an environment variable fx. data = true if the
                      ** path exists otherwise set data = false
if %data%=thrue goto goon 
echo 
echo Wrong data-path - try again !!
goto again
:goon
f:\wp\wp/ps=%answer%
cls
c:
