SVCFIND

The SVCFIND (SVC) service scans the SVC table, locating and displaying information about SVCs.

It also

  • dumps the first 64 bytes of the SVC module from main storage
  • helps you plan the installation of new SVCs

For information about loading SVCs into main storage, see LOADLPA.

Syntax

GUID-76A1313D-60D0-4884-824C-F28B117A883B-low.pngThe parameters are defined as follows:

Parameter

Description

type#

is a one-digit SVC type number (1, 2, 3, 4, or 6)

SVCFIND displays unused SVC table entries that equal the type number.

starting#

is a one- to three-digit SVC number

The display begins with this number. The default is 200.

ending#

is a one- to three-digit SVC number

The display ends with this number. The default is 255.

LIST

displays all SVC numbers in the specified starting number and ending number range

DUMP

displays the first 64 bytes of the specified svc# from main storage

svc#

is a one- to three-digit SVC number

This number cannot exceed 255. The default is 0.

Warning

Note

If no operands are specified, SVCFIND displays all unused SVC table entries, regardless of type number. This option is the default.

Examples

To display SVC table entries for unused type 2 SVC members between 240 and 245, type
