[PCB_FORUM] Re: detect a unsaved layout in Allegro PCB

thx. that helps a lot.

but I cannot find that command in the Allegro Skill Manual ( Version 15.5.1)
Is this an undocumented command ?
Are we allowed to use it ?

btw. if I type that in to the Skill Dev Console, I get the following error
message
---
E- *Error* eval: undefined function - axlSaveEnable
