How to turn off Arbortext Processing Instructions

How to turn off processing instructions in Arbortext Editor

This is the second-most asked question. It’s one of the most common questions we get. It’s so common, there’s a post about it on the Arbortext Code Archive.


On save, Arbortext Editor adds processing instructions, like <?Pub  Caret?>. How do I remove processing instructions (PIs) ?


Turning off the PIs is easy. You change an advanced setting in the preferences:

set writepi=off

It’s documented in help topic #1587.


If you turn off the PIs, you turn them all off. No touchup, no Arbortext extensions, etc. Make sure you really want them off before you turn them all off.
