Chapter 25. XTRAS > USING XTRA LINGO

USING XTRA LINGO

A few Lingo properties and functions help you work with Xtras. You can, for instance, determine whether an Xtra is working simply by trying to use it. If the initial new command does not return a valid object, you know there has been an error. Use the objectP function to determine whether you have a valid object:

xObj = new(xtra "FileIO")
put objectP(xObj)
-- 1
