				compare.c

Purpose:
	Execute compare command:  compare the sequence from the general
	purpose buffer with the sequence from the reference buffer. The
	keywords are: OFF, ZOOM, CORNER.

Input:
	(1) Pointer to MolComplexS structure.
	(2) The number of macromolecular complexes.
	(3) Pointer to RuntimeS structure.
	(4) Pointer to ConfigS structure.
	(5) Pointer to GUIS structure.
	(6) Pointer to NearestAtomS structure.
	(7) The number of pixels in the main window free area.
	(8) Pointer to refreshI.
	(9) Pointer to the remainder of the command string. The command
	    may be given with a list of keywords.

Output:
	(1) The main window mode changed to 5 (default is zero).
	(2) Return value.

Return value:
	(1) Positive (command) code on success.
	(2) Negative (error) code on failure.

Notes:
	(1) This command reinitializes the  NearestAtomS array,  except
	    if at additional keyword is not recognized.
