# ud command

The ud BASIC program invokes the Update
processor to edit ADIs or file-defining items in the dictionary of
the specified file.

The program determines which type of entry is being edited
and presents a different set of attribute names depending on whether
the item is a D-pointer or a standard attribute-defining item (an
a, s or x type item).

## Syntax

```
ud file.reference {item.list}
```
