Basic Aid+ is an 8k toolbox of extra commands that complement Locomotive Basic Considering the relative ease with which the Amstrad CPCs can be given extra commands (or RSXs, Resident System Extensions) it is surprising that not very many toolboxes are available. Base Aid+ is different from most in that it is not supplied as a plug in ROM. and is therefore cheaper.
The program supplies an extra 74 commands. These can be broadly split into three different groups; those which deal with graphics and sound, those which control the printer, and others for programming and debugging.
The graphical commands include 5 extra fonts for printing to the CPC screen. There is a gothic font - which would be handy if you were writing a swords and sorcery game, a bubble style suitable for games, a futuristic font, a stencil "war" type font and a line drawing font.
Another useful graphic command is Spscreen This will split the screen into two modes of your choice. You could have Mode 0 in the top area and Modo 2 in the bottom part of the screen Okay. okay, there are plenty ol magazine listings to do this, but do you really want to go through all that type-in hassle? (Sit down. Mr Monteiro).
Many other commands are smartened up. simplified Locomotive Basic functions. For example. Gpen to set the graphics pen.
The printer commands are simple switches to set different styles and effects on a standard printer These are bold, condensed, double strike, double width, italics, elite. NLQ, proportional. subscript and superscript Using these commands is faster than delving into the printer manual.
The last, and potentially most useful, set of commands are used for programming and debugging. The number of lines in a Basic program, memory free, disabling the escape key. double Poke and Peek are some of the more useful options. An interesting command exists that enables you to scan through memory, printing up the ASCII code (and relevant graphic code for 0-31) at all the bytes between two supplied addresses.
The manual for this program is nothing special; being a collection of photocopied sheets stapled at the corner It explains fairly well what each command does and includes several demonstration programs to illustrate this.
In short, Basic Aid+ is a fair assortment of extra commands which could well prove useful to the Basic programmer. If you want a toolkit extension, but don't want to invest in a romboard. this could well be what you're looking for.
