# System Parameters

'IZ'= | Ignore Maximum Memory Setting

## Description

When the 'IZ' parameter is set, the system will ignore the maximum memory setting defined by either the START directive or the 'SZ'= system parameter.

Use the 'IZ' parameter when converting an application from another language where the values on the START directive may be incompatible with PxPlus standards.

#### Important Note:
Care should be taken when running systems with the 'IZ' parameter enabled as it allows an application to allocate potentially all of the available memory to the process. This can cause system failures and/or severe system degradation.

## Default

Off - Memory use will be limited via START and 'SZ'= settings.
