# tape modifier

The tape modifier retrieves data from
the currently attached tape, rather than the actual data level of
the file. The tape must have been created in a t-dump format and must be positioned to the beginning of the appropriate
tape file. The attribute-defining items specified in the AQL sentence
are retrieved from the dictionary level of the specified file name.

Note: The tape modifier can be used only
with AQL commands that do *not* sort prior to output, such as count, istat, list, list-label, reformat, select, stat, and sum.

## Syntax

```
tape
```

## Example(s)

This example assumes that the
appropriate t-dump media has been attached and
previously positioned at the proper tape file.

```
list invoices with date >= "1/1/04" and <= "12/31/04" tape
```
