Notes and Credits (added by cadams)

This is a basic simulation of Apple II LOGO with a command line. To move forward type "FD 100" instead of return hit the PAGE DOWN or DOWN ARROW. Other commands are BK for back, RT for right, LT for left, HT for hide, ST for show, CS for clear screeen and home. It also has REPEAT. For square brackets use PAGE UP or UP ARROW and N for [ and M for ]. For example REPEAT 4 [FD 100 RT 90]. (Think of UP ARROW as "shift"). This version also allows you to write a simple script. For example, type

TO SQ PAGE DOWN

FD 100 RT 90 SQ PAGE DOWN

END PAGE DOWN

at the end of each line hit PAGE DOWN or DOWN ARROW. To run the script type SQ. This simple script was described by Seymore Papert in his original NSF proposal for Logo. Note that once you start it running it never stops! An alternative method is to write

TO SQ

REPEAT 4 [FD 100 RT 90]

END

The program keeps 3 scripts in memory. WARNING MEMORY IS LOST WHEN THE FLAG IS CLICKED!
