  1. In this text below should not 0x0ff be 0x0f? since there are 4 bits.
  2. Should not the example be 1,17 instead of 1,18? since 17-2 = 15 = 0x0f?
  3. Also, why use C notation and not BASIC i.e. (SA-2) AND $0F?

The upper 4 bits are (SA-2) & 0x0ff where SA is the secondary address.

Examples:

10 REM LOAD VERA SETTINGS
20 LOAD"VERA.BIN",1,18 : REM SET ADDRESS TO $FXXXX

It was an accidental double-tap of the 'f' key.

I agree about the BASIC notation.
