The pibs file contains device specifications for each port.
pb
A pibs item is required for each process executing on the system.
The items in the pibs file define the memory resident hooks of the process workspaces. The pibs file also defines the physical devices connected to the system’s ports, such as terminals, printers, phantoms, or communication ports. The port numbers are the item-IDs.
Device control information is derived from the pibs file and the devices file. The pibs item specifies the device type and the devices item defines device characteristics and drive functions.
| Attribute | Name | Description |
|---|---|---|
| 0 | pib# | The item-ID consists of the PIB number. |
| 1 | location | Physical location of the device connected to the PIB. |
| 2 | device | Item-ID (in the devices file) identifying the specific device on the port (for example, wy-50 terminal). When the port becomes active, it is automatically setup to the device type. |
| 3 | status | Current status of the PIB. It is a display-only attribute called through a program at list time. |
| 4 | abs-fid | FID in decimal of the first frame in the contiguously linked machine code item (ABS area) being executed. It is a display-only attribute called through a program at list time. |
| 5 | pcb-fid | Frame number (FID) in decimal of the process control block (PCB) linked to this PIB. It is a display-only attribute called through a program at list time. |
| 6 | pgm-ctr | Program location and execution stack within the machine code item (ABS area) where the process is currently executing. It is a display-only attribute called through a program at list time. |
| 7 | user | Item-ID (in users file) of the user logged on to this PIB. It is updated at user logon and deleted at logoff. It is used in the accounts file if accounting is enabled. |
| 8 | u-date | Date the user associated with this PIB logged on to this user-ID. It is updated at the same time as the user and is deleted at logoff. |
| 9 | u-time | Time of day the user logged on. Updated at the same time as the user and is deleted at logoff. |
| 10 | MD | Name of the master dictionary file (item-ID in mds file) this PIB is logged onto. It is updated at MD logon and deleted at logoff. This is used in the accounts file if accounting is enabled. |
| 11 | md-date | MD logon date. Updated at the same time as the MD and is deleted at logoff. It is used in the accounts file if accounting is enabled. |
| 12 | md-time | MD logon time. Updated at the same time as the MD and is deleted at logoff. It is used in the accounts file if accounting is enabled. |
