=== Type-Ins ===
* Weekday (Gary Nugent)
* Fancy Text Generator (Richard Turner)
* Sine-wave Writing (Andrew Perry and Andrew Crawford)
* Random Lines (Dak Long Lau)
* Megadump (Pat McDonald)
* Zycloid (J. Smeets)
* Neutron Maze (Tommy Daffin)
=== Problem Attic ===
* Reading the screen - reads a character from the screen, like the <tt>COPYCHR$</tt> command in BASIC 1.1
=== Hot Tips ===
* Hyperweird (Haden Jackson-Robbins)
* Banking from Basic (Alex Aird) - using a firmware <tt>CALL</tt> on the CPC6128 to access its additional memory banks
* Prime numbers (David Pollard) - consists of two listings – one to generate prime numbers, and another to find them
The "Prime generator" listing takes 165 minutes to generate the first 7,500 prime numbers in BASIC 1.1, and longer still – 174 minutes – in BASIC 1.0. The author claimed in his letter to ''Amstrad Action'' that "it takes just under half an hour to run".
== Bugs ==
The version of ''Weekday'' that is modified for the change to the Gregorian calendar in England contains a minor bug; the day of the week for 14th September 1752, the day after the Gregorian calendar was introduced in England, is not calculated correctly.
''Fancy Text Generator'' lacks a <tt>MEMORY</tt> command, so the program could easily be overwritten and stop working or crash.
