I know Pascal well, and I thought I had a pretty good idea of C, but I'm
getting a bit lost in what seem to fairly elementary questions involving C and
the Mac ToolBox.

1) How does one determine if a key is down using KeyMap?  It's simple in
Pascal: an array of booleans, but in the C interfaces it's declared as 
	
typedef struct KeyMap
	{
	long	Key[4];
	}KeyMap;

which is considerably less obvious.

2) How does one return a Str255 from a function?  THINK complains "can't return
array from function"?  But aren't I returning a pointer to the first (Oth) char
of the Str255 if I "return myString"?  Do I need Str255 *MyProc() if I want to
pass back any reference to a Str255 at all?

See, I told you these were weenie. And I'm supposed to learn C++? :->
