hello. I am new to gibbs and need to edit a post. the post processor that is currently active is as follows

Mit MSX 850MS NL2500NLY[ECS] YIML 2295.19.12.pst

I need to edit this for a Star SV-32J with FANUC 18i-T controller. basically the "X" values need switched along with the "Z" values and the G02 need switched to G03 and vice versa. It can be posted using the previous post but has to be edited for the swiss in the Predator cnc edit software which is a pain.
I am familiar with MasterCAM and know how to edit the posts in that software just not the Gibbs software. Please if there is any suggestions it would be beneficial.

thanks
