user is prompted to operate tape controls

1) store source screens in a SEQ file an indefinite number of blocks can be loaded in PLAY mode FLUSH appends all modified buffers to the open file in RECORD mode BLOCK retrieves the nth block from the beginning of tape

2) implement some type of fastloader

3) copy ideas from Fig Forth 1.0 for PET http://cbm-hackers.2304266.n4.nabble.com/Forth-for-PET-WAS-Re-Commodore-8032-SK-tp4656548p4656551.html .d82 image at http://www.idealine.info/CBM/forth.d82

Have a screen buffer area growing downward from top of RAM. Use load, save and verify to save the entire area as a PRG file, ending at $7c00
