uses about 17 k of flash

to do
optimize code for space

remarks

goal is fast execution time, minimal use of ram and intuitive syntax
therefore =>
case sensitive cmds and vars (lowercase uses time and code)
no math hierarchy  (costs ram and execution time, better group with brackets, anyhow better readable for beginners)
(will probably make math hierarchy an ifdefed option)
keywords if then else endif, or, and are better readable for beginners (others may use {})
