+.SH NAME
+CUTEST_cnoobj \- CUTEst tool to determine whether the problem has an 
+objective function or not.
+
+.SH SYNOPSIS
+.HP 1i
+CALL CUTEST_cnoobj( status, input, noobj )
+
+.HP 1i
+For real rather than double precision arguments, instead
+
+.HP 1i
+CALL CUTEST_cnoobj_s( ... )
+.SH DESCRIPTION
+The CUTEST_cnoobj subroutine discovers whether the problem decoded 
+from a SIF file by the script
+\fIsifdecoder\fP. 
+has an objective function or not.
+
+The problem under consideration
+is to minimize or maximize an objective function

+.EN
+The objective function is group-partially separable and all 
+constraint functions are partially separable.
+
+.SH ARGUMENTS
+The arguments of CUTEST_cnoobj are as follows
+.TP 5
+.B status \fP[out] - integer
+the outputr status: 0 for a succesful call, 1 for an array 
+allocation/deallocation error, 2 for an array bound error,
+3 for an evaluation error,
+.TP
+.B input \fP[in] - integer
+the unit number for the decoded data; the unit from which OUTSDIF.d is
+read,
+.TP
+.B noobj \fP[out] - logical
+is there an objective function( .FALSE.) or not (.TRUE.)?
