# uclose command

The uclose command closes a file variable previously opened with the
 uopen command.

## Format

```
UCLOSE FileHandle THEN statement(s) ELSE statement(s)
```

## Description

The command fails if *FileHandle* is not valid. If an error occurs, the ELSE
 clause executes. If the uerror() function is called, the appropriate error
 code is returned.

## Example(s)

These statements open, and then close, the \books\chap1.txt file:

```
FileName="c:\books\chapt1.txt"
UOPEN FileName FOR READ TO FileHandle ELSE
 PRINT "Unable to open ":FileName
 STOP
END
UCLOSE FileHandle ELSE
 STOP
END
```
