Tiny BASIC started out as a way to get a BASIC running in the minimum amount of memory space (~2 KBytes), because RAM used to be very expensive and home computers would only have a few KB of RAM back in the 1970's.

My Tiny BASIC dialect, that I just called "tinyBasic", is similar and loosely based on the Intel 8080 Tiny BASIC written by Li Chen Wang and appearing in Doctor Dobb's Journal of Computer Calisthenics & Orthodontia in the May 1976 issue.

tinyBasic is developed with the iziBasic compiler for Palm OS handheld devices.

The source code of tinyBasic is provided in the download file (please see instructions in the readme file).

Update Description:
v1.1 (04/30/07):

• Minor update of iziBasic's source code to retrieve correctly values like -3 or .5 (before one had to write a=0-3 or a=0.5, when now a=-3 and a=.5 are valid entries)
• Another minor update was to only accept integer values as line numbers
• Ported the iziBasic source code to PP, NaPP and Free Pascal
