!	This file is used to define the scanner status blocks
!	which are used to switch the input context for the scanner.
!	SCANNR has three possible contexts:
!		1) The normal input file (file 0)
!		2) An alternate input (require) file (file 2)
!		3) A character stream imbedded in a SYNONYM definition
!		control comment, which can appear in either input file.
