SYSOPR Macro SYSOPR Macro Use the SYSOPR macro instruction to specify the system operator's
userid, and the userid of the operator who is to receive VM/370 system
dumps. The same userid may be specified in both operands.
The name field
instruction.
must not be specified for the SYSOPR macro
The format of the SYSOPR macro is:
r----------------·----------------------------------------------------------, , Name Operation Operands I I 1 , , I I , I I L- SYSOPR r , ISYSOPER=userid I L J r , I,SYSDUMP=userid I L J r , ISYSOPER=OPERATORI ISYSOPER=userid I L J is the userid of the virtual machine to be assigned to the system
operator. If SYSOPER is not specified, the userid OPERATOR is
used.
The userid is a character string up to 8 characters long.
r , ISYSDUMP=OPERATNSI ISYSDUMP=userid I L J is the userid of the virtual machine whose spool input receives the
system dump file after a system restart. This userid also receives
quest virtual machine dumps produced by the CP command VMDUMP, if
you specify the destination as SYSTEM in the VMDUMP command. If SYSDUMP is not specified, the userid OPERATNS is used. If you
intend to use IPCS, allow this operand to default to OPERATNS or
specify the IPCS userid.
The userid is a character string up to 8 characters long.
The following SYSOPR macro designates the OP virtual machine as the
system operator and directs the system dumps to the CPSYS virtual
machine. SYSOPR SYSOPER=OP,SYSDUMP=CPSYS 172 IBM VM/370 Planning and System Generation Guide

SYSCOR eacro SYSCOR Macro Use the SYSCOR macro instruction to generate the internal control block
called the CORTABLE. The AP operand specifies whether will try
to make use of an attached processor.
The name field

The format of the SYSCOR macro is: r I Name , Operation Operands I I SYSCOR [,FREE=ffff] t ',AP={YES}I I NO I L .J [TRACE=nnn]
L ReSIZE={XXXXXK} yye is the amount of real storage available for This value
limits the amount of real storage used by if it is less than
the total amount of real storage available in the real machine. If
the available real storage is less than this value when VM/370 is
initialized, a message indicating the amount of storage available
is displayed at the operator's console.
The value, xxxxx, is a 3-to 5-digit number that denotes the amount
of real storage in terms of K bytes, where lK=1024 bytes. This
value may range from 384K to 16384K. It must always be a multiple
of 2. The value, yy, is a 1-or 2-digit number that denotes the amount of
storage in terms of bytes, where bytes. This value may
range from to Do not specify a value substantially larger than the size of
real storage, because the generated core table uses a large amount
of real storage.
FREE=ffff
is a 1-to 4-digit number that specifies the number of fixed free
storage pages to be allocated at VM/370 initialization. This
number must be greater than 3; the amount of storage represented
must not be greater than 25% of the value specified for RMSIZE. The recommended value for ffff is one page for each virtual machine
that is logged on, based on the average number of virtual machine
users.
If the FREE operand is not specified, allocates three pages
for the first 256K of real storage and one page for each additional
64K thereafter, not including the V=R size, if any. In AP mode,
the default is increased by Part 2. Defining Your VM/370 System 173
