No, I know about the colon operator and what not, I'm talking about the syntax, just look at this page and you'll see the 'print()' equivalent in this syntx.On May 8, 2013 3:30 PM, "Mason Mackaman" <masondeanm@aol.com> wrote:

gc.paint( gc, output, x, y )So, calling a function that's in the "gc" table with "gc" as the first argument. It's used mainly to make object-oriented programming in Lua easier. In this case, tables behave as objects.
