If you have a lot of strings to juggle, treat yourself
to a string stack. Forth is all about flexibility, right?

When parsing commands for my engineering tools, strings
are indispensable. But I use a ringbuffer, not a stack.

Nowadays I tend to use temporary redirection of I/O to
(large) strings with <$$ ... $$> ( -- c-addr u ). For
short sequences nothing beats $+ .

A ring buffer for holding strings is a classic for Forth
systems. For larger string sequences, such as data in XML
format, ring buffers tend to be overwritten. But that's
an application-sprecific implementation detail, not a
topic for a standard.

Ring buffers should manage their pool appropriately. That's
a quality of implementation aspect. Slightly more dangerous
is using their strings permanently. It assumes quality at
the other side of the keyboard.

You're welcome :)

A relative never cleaned their email inbox. For the last
month any message sent bounced with 'mailbox full'. Their
solution was to pay for a bigger inbox.

If you set aside 1 Gbyte of a 8 Gbyte for a circular string
stack, why don't you do like me? Permanently allocate all
strings in the dictionary. This is a so called memory leak,
but this is not so bad compared to wasting 1 Gbyte up front.
Works well together with MARKER, I'd see better than a circular
string set.
