Bugs

ST BASIC has many bugs. '' Compute!'' in September 1987 reported on one flaw that it described as "among the worst BASIC bugs of all time". Typing x = 18.9 results in

function not yet done
System error #%N, please restart

Similar commands, such as x = 39.8 or x = 4.725, crash the computer; the magazine described the results of the last command as "as bad a crash as you can get on the ST without seeing the machine rip free from its cables, drag itself to the edge of the desk, and leap into the trash bin". After citing other flaws (such as ? 257 * 257 and ? 257 ^ 2 not being equivalent) the magazine recommended "avoid ngST BASIC for serious programming". Regarding reports that MetaComCo was "one bug away" from releasing a long-delayed update to the language, it jokingly wondered "whether Atari has only one more bug to eliminate from ST BASIC or one more to add".

Alternatives

The relatively low quality of ST BASIC quickly opened up a market for third-party BASICs on the ST. FaST BASIC and GFA BASIC were two of the first of these third-party BASICs to be released. As these BASICS were not free, a program written in one of these BASICs could only be listed and run if the user had that BASIC. However,
