SUBROUTINE AX_GFLD  ( report, lenr, irptr, field, lenf, iret )
C************************************************************************
C* AX_GFLD								*
C*									*
C* This subroutine returns the next field from REPORT that begins at	*
C* or after pointer IRPTR.  The fields in REPORT must be separated by	*
C* blanks.  Any blanks between IRPTR and the start of the next field	*
C* will not be returned.  On output, the pointer IRPTR will point to	*
C* the first non-blank character in REPORT after the returned field.	*
C*									*
C* AX_GFLD  ( REPORT, LENR, IRPTR, FIELD, LENF, IRET )			*
C*									*
C* Input parameters:							*
C*	REPORT		CHAR*		Report 				*
C*	LENR		INTEGER		Length of REPORT		*
C*									*
C* Input and output parameters:						*
C*	IRPTR		INTEGER		Pointer within REPORT 		*
C*									*
C* Output parameters:							*
C*	FIELD		CHAR*		Next field 			*
C*	LENF		INTEGER		Length of FIELD 		*
C*	IRET		INTEGER		Return code 			*
C*					  0 = normal return 		*
C*					 -1 = no more fields in	REPORT	*
C*					 -2 = LENF for next field is	*
C*					      larger than MXLENF	*
