This Natural profile and session parameter specifies whether or not structured mode must be used.

Possible settings	ON	Forces the use of structured mode syntax.
	OFF	Programming can be done in either structured mode or reporting mode.
Default setting	OFF
Dynamic specification	yes
Specification within session	yes
Applicable statements	none
Applicable command	GLOBALS
Application programming interface	USR1005N	See SYSEXT - Natural Application Programming Interfaces in the Utilities documentation.

Notes:

1. If structured mode (SM=ON) is specified by profile parameter SM, an attempt to change this setting with system command GLOBALS and session parameter SM will be rejected (Reporting mode not permitted).
2. Within a Natural session, the profile parameter setting SM=OFF can be overridden by the session parameter SM=ON.
3. Under Natural Security, the setting of the mode option in the library's security profile determines whether the SM profile parameter can be used; see also Programming mode in the Natural Security documentation.
4. Under Natural Security, this parameter may be disabled by Natural Security to the effect that structured mode is invariably in effect for a given library.
