How to compare a positive and negative value and determine which is larger

[Jarrod Phillips]

Hi All,

As the topic suggests, is there a way to compare two values, one being a positive value and the other a negative, and determine which is the larger value? For example, I have two values, the first is 589 and the second is -788. I want to compare the values irrespective of whether it is positive or negative, in this instance the -788 is the larger value.

OR

Is there a GDL command to easily swap a value from being negative to positive?

Thanks in advance!

Regards,

Jarrod
