The what command displays the system configuration and the status of system locks, specified lines, spooler, and printers.
what {port.number{-port.number}} {’user-ID’} {(options)}
| ’user-ID’ | Outputs where status only for users of the specified user-ID. | |
| {port.number{-port.number}} | Outputs the status for the given port, or a range of ports. | |
| options | l | Suppresses display of lock status. |
| n | No pause. Suppresses the pause at the end of the page on the terminal. | |
| p | Directs output to the system printer, via the spooler. | |
| s | Suppresses the display of sp-status. | |
| w | Suppresses the display of where output. | |
| z | Displays the where status for all lines, including inactive lines (those which are not currently logged on). | |
The system configuration information displays:
| memory | Amount of memory allocated to the D3 virtual machine, in kilobytes. |
| pibs | Number of process identification blocks. This includes communication lines for terminals and serial printers, spooler, phantom processes, and scheduler. |
| pcb0 | FID for the PCB for line 0. |
| sysbase/mod | Base FID and modulo of the master dictionary’s (system) file. |
| maxfid | Last addressable FID on the system. |
| available | Number of frames available in overflow. |
| dfsize | Number of bytes available per data frame. The actual frame size is a bit larger. A dfsize of 1000 indicates an actual frame size of 1024. A dfsize of 2000 indicates an actual frame size of 2048. A dfsize of 4000 indicates an actual frame size of 4096. |
In addition, what uses the where command to display the current status of each line, the list-locks command to display the system lock table, and the sp-status command to display the spooler and printer status.
