Is there documented somewhere a list of all the COMPILE time error messages?
and if they apply to all or only specific platforms?
There isn’t
Closest you’ll get is the list of scripting errors since it uses the same language
http://documentation.xojo.com/index.php/Scripting_Errors
I did find this… (and I had found the scripting one)
http://documentation.xojo.com/index.php/Category:Errors_Error_Messages
