This Natural profile parameter controls the automatic overwriting of print and work file access method assignments during session initialization according to the data set definition in the job control.

Note:
See also the AM subparameter of the macros NTPRINT and NTWORK.

Possible settings	ON	All print and work file data sets are automatically assigned to the batch access method AM=STD if the logical data set name (defined by the DEST subparameter) is defined by job control.
	OFF	Automatic print and work file assignment to AM=STD is done only if the file is not assigned to another access method; for example, AM=NAF. Note: If AM=OFF is specified, no automatic assignment is done. Specify AM=0 if you want to reset the access method type and to allow automatic assignment.
Default setting	OFF
Dynamic specification	yes
Specification within session	no
