What are the consequences of declaring a local variable within
a function called "thePort" and setting it explicitly with
GetPort(thePort). I find the following code in some examples
in LSC TransSkel (release 2.0)
DoWClose ()
{
GrafPtr thePort;
MenuHandle m;
Integer i, mItems;
Str255 iTitle, wTitle;
GetPort (&thePort); /* grafport of window to be closed */
Seems kind of strange to me....

Nothing wrong with it at all. Brushup on your scoping rules and look at the program again... -Kelesi -- ------------------------------------+------------------------------- From the Macintosh of: Kevin Sitze | Disclamer: Who the heck needs | a disclamer?
