Palo Alto Tiny BASIC is one of the most popular of the many versions of Tiny BASIC. It was developed in 1975 by Li-Chen Wang.

Features

Palo Alto Tiny BASIC has some features that distinguish it from other Tiny BASICs:

• The FOR...NEXT loop. Like in Microsoft BASIC, the upper and lower bounds of the loop are set on loop entry, and did not change during the loop, so if one of the bounds is based on a variable expression, changing the variable do not change the bound. The STEP modifier is optional.
• The ability to place several statements on a single line. Palo Alto Tiny BASIC uses the semicolon ; to separate statements, rather than the colon : common in BASICs.
• A single numeric one-dimensional array, with the variable name @.
• The statement STOP in addition to END.
• The use of # for not-equals in comparisons, as opposed to <>.

Implementations

Palo Alto Tiny BASIC was adapted for many implementations:

• 3K Control Basic for Cromemco (by Li-Chen Wang)
• Level I BASIC (1977)
• Sharp PC-1211 BASIC (1980)
• Astro BASIC (1982, by Jamie Fenton)
