:Why doesn't this work?  If the file doesn't exist, the appropriate
:error message is printed;  if the file does exist, the machine
:promptly aborts with guru 81000009.xxxxxxxx.

:   if (! Examine (lock, fib))
:      {
:      FreeMem (fib);

	That should be:

	FreeMem(fib, (long)sizeof(struct FileInfoBlock));

	FreeMem() takes two arguments, the pointer and the block size.  If,
on the otherhand, you used malloc(), free() requires only a pointer.  BTW,
this is a *feature* of EXEC's memory system ... Allocated memory takes no
overhead.
