The June 1987 issue of ''[[Amstrad Action]]'' saw the Type-Ins section advertised on the cover of the magazine for the first time, with the headline, "Magical Type-Ins". The cover is based on the type-in ''Card Trick'' by Simon Capp, and shows the keys of a CPC6128 keyboard flying into the air and transforming into playing cards.
This issue also saw some changes to the Type-Ins section. From this issue, a detailed, step-by-step explanation of how one particular type-in worked was provided. The featured program in this issue was ''Card Trick'' (as suggested by the cover), and three of the six pages in the Type-Ins section were devoted to examining it. Later issues would refer to this feature as the "Program made plain".
=== Type-Ins ===
* Card Trick (Simon Capp)
* Textdump (Nigel Magowan)
* Serpent (T. Magee) - requires BASIC 1.1, as it uses extra parameters in the <tt>MOVE</tt> command
* Fuzzy (David Hudson)
* Triangles (Dale Clinton)
* Filecopy (Martin Schroeder)
* Random Symmetrical Patterns (Derick Braithwaite)
* Controlling Patterns (Alex Gough)
* Star-dodging (Rajiv Gatha) - a game written in one line of BASIC
* Rally (Frederick Akinlawon and Jensen Akinlawon)
=== Hot Tips ===
* A bugs story (Richard Hodges) - displays a secret story hidden on the disc version of ''[[Mini Office II]]''
* Scrolling the screen (literally) (David Hall) - scrolls the screen from left to right using the [[CRTC]]
* Italic Characters (Alastair Scott)
* Thin Characters (Alastair Scott)
* Bold Characters (Alastair Scott)
Simon Capp claimed that ''Card Trick'' was a "world first" on the computer. However, ''Amstrad Action'' published an item in the Amscene section of the [[Amstrad_Action,_Issue_22,_Jul_1987|July 1987]] issue stating that several readers, as well as the professional computer magician David Hambly, had informed them that this was not the case.
''Amstrad Action'' mentioned that ''Serpent'' only works on CPC664 and CPC6128 machines, and suggested removing the extra parameters in the <tt>MOVE</tt> command to enable it to work on CPC464 machines as well. However, this does not produce the same effect on the screen.
The Akinlawon brothers also programmed the game ''[[Astroball]]'', which was published by [[The Power House]] in 1988.
== Corrections ==
A correction to ''Filecopy'' was published in the [[Amstrad Action July 1987|July 1987]] issue (#22), which fixed a problem where files could not transferred between drives A and B.
A correction to ''Rally'' was published in the [[Amstrad Action August 1987|August 1987]] issue (#23), which fixed two problems. One of these prevented the screen from scrolling and made the game unplayable, and the other caused the program to <tt>GOTO</tt> a non-existent line number after the user had completed the game successfully.
== Bugs ==
''Thin Characters'' and ''Bold Characters'' were printed incorrectly. ''Thin Characters'' actually produces bold characters, and ''Bold Characters'' produces thin characters.
