Re: How robust is INCLUDE

I wonder if the following code is (partially) ANS compatible, and
if it is easy to understand what it does, especially the word MAIN3.

There is no definition of MAIN3 in what you posted, only a use, so no.

What I need is a word that is passed parameters that define an index
into an array that is not allotted yet. So neither the index nor the
base address
can be pre-computed.
When the word executes (after much more code which
finally sets up the data), it should access the array to fetch a byte at
the indexed position.

From this description, what's wrong with

: array-c@ ( c-addr uindex -- c ) + c@ ;

?  But I expect that I missed something about your requirements.

In general, if you want a program to be easily understandable, avoid
iForthisms (especially where standard alternatives are
straightforwardly available.  Avoiding LOCALS| is also a good idea.
It's unintuitive and therefore harder-to-understand order of locals
was the reason why {: was standardized.
