Extended Basic

This package is not really Extended BASIC of the IF ... THEN ... ELSE, or PROC variety. It's a toolkit offering 10 extra facilities, which are accessed by a single key-press following an asterisk. The whore command is then printed on the screen.

AUTO line number, RENUMBER, line DELETE, TRACE. and list VARIABLES are offered, together with a real-time CLOCK, MEMORY left. EXAMINE a header, FIND a string in your listing, and SCROLL control. It occupies about 4.8K, sitting above a suitably lowered RAMTOP, and is presented in a strong box with a clear, helpful manual.

It's very easy to use, and it really is a joy when developing your own programs. A few moans though. What’s the point of a real-time clock, and one that loses time when you load a new tape? Similarly, scrolling is easily controlled by poking the system variable at 23692. p> If space is at a premium then this might be for you. This toolkit does not appear to be compatible with the Microdrive; it crashes, so if you're thinking of upgrading, it will have limited use.
