RE: FORTH for the SHARP PC-E500 (S)
It's a round thing: an extensive programming language including a detailed manual (65 pages are printed out). Thank you for that Rob, I'm thrilled. Now there are floating point numbers, so Forth go ahead and draw a sine curve in the display.

3.141592654e FCONSTANT PI

: fdx        \ step size in radians 
 4e PI F* 240e F/ ;

I               \ x of pixle-coordinate
I S>F fdx F*    \ x in radians
FSIN 1e F+      \ y between 0 and  2
15.5e F*        \ y between 0 and 31

From Forth500 with INCLUDE COM: loaded and started. (I previously set the PC-E500 to RAD in BASIC mode with Shift-DRG.)
