script help

[TKOFaith]

Greetings!

I have an array of hits from a surface and have assigned V2 to be the MAX of the array and V3 to be the MIN of the array. I would like to have a script determine if the values of V2 and V3 are positive or negative, and then determine the range of values--if they are both positive, both negative, or a combination thereof.

I appreciate the help!

Blessings!

What's you ultimate goal? to evaluate the profile variation of the entire surface?
Your assign for RANGE can be something like this (presuming you want it to always output as a positive value)

assign/range=if(v2>0, if((v2-v3)<0,ABS(v2-v3),v2-v3), if(v3>0,abs(v2-v3),abs(v2+v3)) )

note I didn't prove this out in pcdmis, just jotted each of the 4 possibilities out on paper and worked through each one. I would definitely test all of the possible situations out before setting it in stone.
