Figure 6: MODE SELECTION FRAME screen

By making entries in this frame and pressing the ENTER key, you can switch to other frames or execute various basic functions.

FUNCTION =>	The desired function can be selected by entry of a number listed in the EXECUTION column or a letter combination listed in the SELECTION column.
SELECTION =>	After entering the appropriate letter combination you can switch to the following SVP frames:

LD	PROGRAM LOAD	Load BS2000	"(LD) PROGRAM LOAD FRAME: BASIC"
ST	STATUS DISPLAY	Display status	"(ST) STATUS DISPLAY FRAME"
MA	MANUAL OPERATION	Manual operations	"(MA) MANUAL OPERATION FRAME"
AD	ALTER/DISPLAY	Alter/display storage/register	"(AD) ALTER/DISPLAY FRAME"
ME	MESSAGE	Display message	"(ME) MESSAGE FRAME"
CH	CH/SUBCH STATUS	Display status of channel /subchannel	"(CH) CH/SUBCH STATUS DISPLAY FRAME"
AU	AUXILIARY	Auxiliary controls	"(AU) AUXILIARY FRAME"
MF	MSF	Display FLAG codes	"(MF) MSF FRAME"
PA	PERORMANCE ANALYZER	Performance analysis	"(PA) PERFORMANCE ANALYZER FRAME"

EXECUTION

The following function is executed after the corresponding number has been entered:

CAUTION!

The functions are executed according to the entries in the CPU SELECT and STOP/START MODE fields (see table on next page)!

1	CPU STOP	stops either the CPU selected in the CPU SELECT and STOP/START MODE fields or all CPUs
2	INTERRUPT	creates an external interrupt for the CPU selected in the fields CPU SELECT and STOP/START MODE
3	TOD ENABLE	time entry is enabled
4	SYSTEM RESET	all CPUs, channel processors, channels and controllers are reset
5	SYSTEM RESET CLEAR	as 4; in addition, the working memory is erased
6	STORE STATUS	selected CPU is stopped, the status is stored
7	RESTART	starts the system again (this function is only possible if the operating system is restart-capable) In VM2000 mode a restart of the monitor system (with SLED) will be initiated.

CPU SELECT =>	A particular CPU can be selected here for the functions in the EXECUTION selection menu (see the previous page). The CPUs available are displayed in the two lines below this.
0 ... F	Selection of a particular CPU
STOP/START MODE =>	This can be used to indicate whether the functions in the EXECUTION selection menu are to be carried out for all CPUs or only for the CPU in the CPU SELECT field.

1	ALL CPU	all CPUs are selected
2	TARGET CPU	only the CPU selected in the CPU SELECT field is selected

The following table shows all the functions that can be meaningfully combined:

Function	CPU SELECT	STOP/START MODE	Effect on:
CPU STOP	-	1 All CPU	all CPUs
	0 ... F	2 TARGET CPU	selected CPU
INTERRUPT STORE STATUS RESTART	0 ... F	2 TARGET CPU	selected CPU
TOD ENABLE SYSTEM RESET SYSTEM RESET CLEAR	-	-	all CPUs
