# System Parameters

'KF'= | Keyed File Format

## Description

To set the default format type for creation by the KEYED directive.

Where:

| 'KF'=0 | The KEYED directive always creates VLR or FLR-based files.
| 'KF'=1 | The KEYED directive creates EFF formatted files with a 2GB limit.
| 'KF'=2 | The KEYED directive creates EFF formatted files without the 2GB limit on platforms that provide Large File Support (LFS), 64-bit addressing. Setting this parameter on a system that does not provide LFS will automatically change to a 'KF' value of 1.
