# u command (FlashBASIC Debugger)

The u command removes from the trace
table a given variable, or all variables, previously specified with
the t command.

## Syntax

```
{flash.routine.name:} u {variable}
```

## Description

A minus sign displays for each
trace table entry successfully removed from the table. The u command, followed by pressing ENTER, clears all trace
table entries.

## Example(s)

This removes the trace on the
client number variable from the table.

```
*uclient.number
```
This removes all traced variables from the table.

```
*u
```
Warning: *flash.routine.name* can only be specified if the program has been optimized through
the FlashBASIC compiler. When *flash.routine.name* is specified, the corresponding debugger command
is executed against the specified routine. The colon separating *flash.routine.name* and the debugger command
is required.
