4.5 Formatting

The FMT command performs correctly except in the case FMT 15,n, where the correct number of figures is displayed, but the mantissa is rounded to one decimal place less than it should be. example of this occurs in Chapter 4, where the result of doing:

FMT 15,2: PRINT 567.988

actually gives 5.70E+02, not 5.68E+02 as it should.

Modify 316B (was 03) to 04 E6 0F 3C C9 E5 E6 0F 3C 21 94 10 86 E1

4.6 EVAL

The use of the EVAL function on a NUL$ has a catastrophic effect.

Modify 24D6 (was 0B) to D5 ED B0 1B

4.7 Output devices

As stated both device 1 and device 2 may be used for a serial device. However, device 2 does not include the handshake facility of device 1 to allow for those applications where it is not required. A simple modification to the IO list would allow either the removal of the handshake from device 1 or the inclusion of it in device 2.

4.8 Manual

1. Our daisy wheel printer insists on treating the exponentiation symbol (up arrow) as a 3/4 – you may find instances in the manual where this has not been corrected.
2. In Chapter two the cursor movement keys should be indicated by the appropriate arrows in the single quotes.
3. In Chapter 3 page 19 the assignment LETAA=1+2*3/4 should of course assign the value 2.5, not 4.5, to AA.
4. The format of the IOLIST given in Chapter 4 in the first 50 copies of the manual is incorrect – the input and output devices are transposed. The list should read:
   
   
   
   
5. In Chapter 4 the example program given under the description of SEP should use the variable MNTH, not MONTH (MON is a reserved word).
