5.44 LPARNUM (LPAR
identification number)

5.44.1 Function

The LPARNUM system parameter sets the LPAR identification number. It specifies the one- or two-digit
hexadecimal LPAR identification number stored by the STIDP instruction, or BASIC. If a one-digit number
from 1 to F (hexadecimal) is specified, then STIDP stores a format-0 CPU ID, unless a subsequent
“CPUIDFMT 1” statement is specified. If zero or a two-digit hexadecimal number, except 10 (hexadeci-
mal), is specified, then STIDP stores a format-1 CPU ID. For LPARNUM 10 the current CPUIDFMT is not
changed. If LPARNUM is BASIC, then the STIDP instruction stores a basic-mode CPU ID. The default is
LPARNUM 1 with a format-0 CPU ID.

5.44.3 Parameter

BASIC

Specifies that STIDP stores a basic-mode CPU ID.

1

Specifies the one-digit hexadecimal LPAR identification number. The STIDP in-
struction stores a format-0 CPU ID. This is the default.

1 … F

Specifies the one-digit hexadecimal LPAR identification number. The STIDP in-
struction stores a format-0 CPU ID, unless a subsequent “CPUIDFMT 1” statement
is specified.

0

Specifies 0 as LPAR identification number. The STIDP instruction stores a format-1
CPU I
D.

nn

Specifies the two-digit hexadecimal LPAR identification number (except 10 hexa-
decimal). For LPARNUM 10 the current CPUIDFMT is not changed. The STIDP in-
struction stores a format-1 CPU I
D.

Example 1:

Set the LPAR identification number to x’21’ (Format-1 CPU ID).

LPARNUM 21

Example 2:

Set the LPAR identification number to x’A’ (Format-0 CPU ID).

LPARNUM A

Example 3:

Set a basic-mode CPU ID.
