These are logical functions which return either 0 or 1 if the
corresponding error has occurred. Only one of them can have the value 1
at any time.

**NOTE 1**

These functions are not affected by REPORT.

**NOTE 2**

On Minerva pre v1.98, the ERR\_XX functions were returning 1 if any higher
error had occurred!!

**WARNING**

The JS ROM version of ERR\_DF had a bug which crashed the system when
used. All later operating systems and Toolkit II, the THOR XVI, the
Amiga-QL Emulator, TinyToolkit, and BTool fix this.
