# System Parameters

'FF'= | File Format

## Description

Defines the format of information returned by the FID( ) function. Possible formats are:

Format | Returns FID Compatible With…
0 | PxPlus standard format
1 | Thoroughbred® emulation
2 | Rexon emulation
3 | BBx® emulation
4 | Enhanced BBx® emulation Sequential files are reported as binary files for the FID( ) function. File type will be set to $03$ rather than a $01$ in position (1,1) of the FID.

## Default

'FF'=0 for PxPlus standard format

#### Note:
When the 'FF' parameter is set to 0 or 4 and the 'PO' parameter is switched On, the FID( ) and FIB( ) functions return the original path used when the file was opened as opposed to the full system pathname.

The FID( ) and FIN( ) key descriptor layouts will be changed whenever there is a change to the 'FF' parameter.
