# case-file command

The case-file BASIC program converts
the case of items to either uppercase or lowercase.

This invokes the conv-case command
and passes it the e, q, u, and o options.

If the file reference
is omitted, the process prompts for it. If it is provided, the process
prompts Dictionary level?. Answering Y, causes the process to affect the dictionary of the
given file.

As the items are issued with the case command, the item-IDs display on the screen.

## Syntax

```
case-file {file.reference}
```

## Example(s)

Converts all the item-IDs in
the test file to uppercase.

```
case-file test
dict level file y,n? n
```
