-
- Forth uses blocks because it was almost always used in embedded
- controllers and on standalone computers which had little or no
- operating system.
-
- It is nuts to suggest that blocks were implemented because they were
- thought superior to text files and to do so is rewriting history.

-
- There is no reason that that should occur. There are many Forths,
- my own JForth included, that support both.

-
- Not at all. Simply change the interpreter such that it considers
- the end-of-line character or sequence to be another blank character.
- (y'know... the unconditional delimeter, most consider TAB, too).
-
- That's 99% of what's needed to get a Forth to work with
- files.

-
- Not using text files will indeed insure that many folks will never use
- any Forth tools.

-
- Forth is not an operating system. It provides an execution
- environment on standalone computers, but it is no operating system.
- Nothing but Forth can operate under it's auspices.

-
- Can you point me to one I can use on my Amiga or Mac? One that
- uses some IPC to interface with popular applications? One that
- provides a full GUI with resizeable windows, menus, graphics,
- photo-quality storage...

-
- Usre of blocks in no way increases one's efficiency. In fact, it hinders it
- because you have to develop all your own print software, backup software,
- stuff that normal OS files live easy with.
-
- It's a helluva lot easyier to insert a new function in the middle of
- your program with files.
