# System Parameters

'WD'= | Defer File Writes

## Description

Defers all file writes until nnn updates have been done, the file is closed, or an INPUT is requested from channel #0 (terminal).

#### Note:
The 'WD' parameter only affects Keyed file I/O.

Performance can be improved in single user environments if the 'WD' parameter is set high.

## Default

'WD'=10000 in a single user environment under Windows; otherwise 'WD'=100.

## Example

set_param 'WD'=10000
