thank you thank you PD list.(in particular, Claude) I am constantly amazed by this community. 
You couldn't get better support if you paid for it.

for my next question...

is there a object that performs the opposite of [abs]?


[abs] can give me 15 when i have -15, for example, but I would like to get  -15 when I have 15.

any ideas?


thanks so much
