| 1. use some external preprocessor to inline and remove constants in the forth source before compiling This is not an unreasonable thing to do. I believe Druzyek wrote a tool to replace all names (variables, constants, words) with short names (not quite what ... |

| Hi pdragon, Tali Forth 2 is a rather large Forth. While it is possible to fit it in 16K, I don't think it would be a great experience to get it down to 8K. Tali Forth 2 is designed for systems with 32K ROM (or RAM if loading it into ... |

| ... which I'm using to compile words for my app, but don't need/have space for them at runtime since I need to load a large data segment. I read in gforth docs (below) that there's no standard way to use #define style constants that are inlined and discarded after compilation. So i'm looking for ... |

Yes, you are programming to create the exact HLL that does the job you need done, so it covers the range from low level programming extending the underlying capabilities through to high level programming. |

| My Fleet Forth's INTERPRET passes the string returned by WORD to a deferred word I/C ( interpret/compile ) which is normally vectored to (I/C) . This allows me to define [IF] [ELSE] and [THEN] like so. :NONAME ( NL1 ADR -- NL2 ... |

Since mine was DEFERed, it doesn't show up as IMMEDIATE until IS, otherwise it would have been execut... |
