6. Routines of existence

CALL RSEXIS (names, irets)

IN	nomsd	K8	data structure name RESULTAT
OUT	iret	I	return code: = 0, the structure exists; ? 0, the structure does not exist.

Verification of the existence of a structure SD_RESULTAT.

CALL RSEXPA (names, icode, name, iret)

IN	nomsd	K8	data structure name RESULTAT
IN	icode	I	= 0, access variable = 1, parameter = 2, access variable or parameter
IN	name by	K16	name of the access parameter or variable
OUT	iret	I	return code: = 0, the name does not exist; = 100, the name exists.

Checking the existence of a parameter name or an access variable name in a SD_RESULTAT structure.

CALL RSVPAR (name, order, name, par, ipar, rpar, kpar, iret)

IN	nomsd	K8	data structure name RESULTAT
IN	iordr	I	order number
IN	name by	K16	name of the parameter to check
IN	ipar	I	parameter value if integer
IN	rpar	R8	parameter value if real
IN	kpar		parameter value if character
OUT	iret	I	return code: = 0, it is not a parameter = 100, the parameter value is correct = 110, the parameter value is not correct

Checking the existence of a parameter name and its value for a given order number in a SD_RESULTAT structure.
