properties that are not set

[Wim Bervoets <wi...@iconmedialab.com>]

Hello,

I read properties in from a file. I want to know how I can test if a
property has been set/hasn't been set.
Eg I have:

1=Wim
2=Tom
3=Stefan

So I use {$1}, {$2}, {$3} and create a directory with that name each time.
Now {$4} is not set so I would like to be able to stop creating directories
then (and stop checking if {$5}, {$6},... has been set)

Is this possible ?

Wim
