Write current directory in a text file

In a batch program I have:

echo Date >c:\users\...\testecmd.txt

Writes the current date to a text file.

Assuming I do not know where the directory in which the self executable is, how do I get it to call the Current Directory instead of " c: \ users ... \ testcmd.txt "and write this same directory instead of Date p>

echo "c:\Diretorio\atual\" >c:\diretorio\atual\testecmd.txt
