It's funny how things come back. It's not much but since last blog I have managed to make some nice and useful words in Forth.. My implementation of SEE is borked and I have not yet even started on writing the in.line assembler but since it's been years on should not expect miracles.

words .name % u%. %. $ u$. $. binary dump dumphex dumpasc ldump .s S.S $8. $4. $2. .r sign #s #> <# # hold hld abs spaces

Number formatting <# # #S sign hold #> are based on "All About Forth", Glen B. Haydon, Mountain View Press updated towards ANS Forth .. Rest are my own.

After a long time I have decided to start coding with Forth. It's kinda amazing language but I don't like to use it on normal PC class systems. IMHO it's a lot better for smallish Embedded hardwares .. like for example Parallax Propeller demo board I have been having over a year now (mostly unused, I have been way too busy). There is quite nice Forth (named PropellerForth) that is 10 kilobytes binary and runs native on that board.

There are only Serial port connection (with USB-ser converter) and not much storage on the board (32kB eeprom, having Propller boot image), but I'm hoping to add some auxilary memory and forth+asm code for in chip videodisplay+keyboard.
