# uf070 user exit

The uf070 user exit starts and stops
multiuser mode, and returns information about the number of serial
ports, PIBs, phantom PIBs, licensed users, users logged on, and the
maximum number of users that can log on.

## Syntax

```
var = oconv(function, ’uf070’)
```

## Description

Setting the system in single-user
mode prevents more users from being able to log on. Users currently
logged on are not affected.

| function | S | Starts single-user mode. |
| --- | --- | --- |
| M | Starts multiuser mode. | |
| "" | Retrieves the current settings. | |
The returned string consists of six values
in this order:

| 1 | SIO | Number of serial ports, and an initial character (s or m) indicating if the system is currently in single or multiuser mode. (The number of serial ports is not returned on UNIX-based systems.) |
| --- | --- | --- |
| 2 | PIBS | Number of PIBs available for serial devices, in hexadecimal. |
| 3 | PHANTOMS | Number of PIBs available for phantom jobs, in hexadecimal. |
| 4 | ULIC | Number of licensed users, in hexadecimal. |
| 5 | ULOG | Number of users currently logged on, in hexadecimal. |
| 6 | UCEIL | Maximum number of concurrent users permitted, in hexadecimal. |
There can be more ports than licensed users.

## Example(s)

```
x = oconv("", "UF070")
print "The current number of users is: ":xtd(x<5>)
```
