				execute_command1.c

Purpose:
	Parse and execute command.  Refresh the message  (reset or fill
	with a new content). This function is capable to execute garlic
	scripts.

Input:
	(1) Pointer to MolComplexS structure, with macromol. complexes.
	(2) Pointer to the number of macromolecular complexes.
	(3) Pointer to the next macromolecular complex identifier.
	(4) Pointer to RuntimeS structure, with some runtime data.
	(5) Pointer to ConfigS structure, with configuration data.
	(6) Pointer to GUIS structure, with GUI data.
	(7) Pointer to pointer to NearestAtomS structure.
	(8) Pointer to the number of pixels in the main win. free area.
	(9) Pointer to refreshI.

Output:
	(1) The latest command executed.
	(2) Return value.

Return value:
	(1) Positive on success (command code).
	(2) Zero, if command string is empty.
	(3) Negative on failure.

Notes:
	(1) The value of refreshI  (*refreshIP)  may be changed in this
	    function or in some function called by this function. It is
	    checked in  EventLoop_  (see event_loop.c).  It is  assumed
	    that  refreshI  is updated no more  than once in each event
	    handling function. If this is not the case, the care should
	    be taken to avoid refreshI overflow.

	(2) The command string is converted to uppercase. Do not forget
	    that  file names are  case sensitive.  Use the copy  of the
	    original command string to prepare the proper file name.
