simple post question

[Fred from Université de Sherbrooke]

I'm working on a post and want to reverse the z output (I want it always positive). Can anybody help me on this. I've try:

pzcalc

zabs = -z

But no result...

Thank's for your help!!

Fred,

In your post block PZCALC you probably want to do something like this:

pzcalc

zabs = abs(z)

#zabs # Remove the # at the begin of

# this line to output zabs when

# PZCALC is called.

Of course, I am assuming that zabs is a defined variable and has a formating statment such as: fmt Z 1 zabs

The abs function will alwasys return a positive value.

Is this what you were looking for?
