# System Parameters

'+C' | Enable External Program Cache

## Description

The '+C' parameter controls the use of the external Program Cache Manager. During system initialization, if the Program Cache Manager is detected, this parameter will be set.

Resetting this parameter will cause the system to disregard the use of the Program Cache Manager.

(The '+C' system parameter was added in PxPlus v6.30.)

## Default

The default setting is determined by the presence of the Program Cache Manager.
