HOW-TO Limit the number of files created

[[email protected]]

I am writing a macro that will automatically create a file BUT I want to limit the number of files that the folder will hold to three.
So the macro will firstly determine how many files are in the folder and create a new one IF there are only two files.
Could someone provide me with a simple example of this? (or point me to the documentation for this)
AND AS ALWAYS, this is GREATLY appreciated!

Gintaras, SORRY to request again, but I'm away from the desk for the rest of the day & am afraid I will get stuck for the whole weekend and not be able to continue.
MY REQUEST: can you revise your above code and:

what I want to do is determine IF folder "C:\folderName" has less than 3 file
and
then simply display an 'out' message of "less than 3 files"
or
if more then simply display the message of 'more than 3'

I don't want to create a file for now. If you do this I think I can easily do the SPECIFIC file create task from my end.

THANKS AGAIN!!!!!!!!!

a.len is the number of files.

if(a.len<3) out "<"
else if(a.len>3) out ">"
else out "="
