# f.modulo command

The f.modulo command in the DM account
calculates a file modulo, based on estimated file characteristics.
The f.modulo command prompts for the number of
items, item-ID size, and item size.

This returns a recommended modulo, taking into concern
the frame size of the machine and inline/pointer items.

CAUTION: Specifying a large item-size (greater than 85% of
the frame size) results in items being computed as pointer items,
which produces a very small modulo.

## Syntax

```
f.modulo
```
