Quick question re the maths operators which whilst specific to FIF could apply to others I suppose.

The zeddy computes and displays to 8 decimal figures but FIF/Forth to 10 (with reasonable scaling) so does FIF use it own standalone maths operators or does it pinch something from zeddies ROM then add something of its own?

Just curious as to how these things work.

It has its own m/c routines to do a 32x16 divide and a 16x16 multiply. The Forth maths words ultimately feed off those two routines.

FIF 1.03 is now available.

This is a bugfix release. Also note that a few of the screen files have had minor edits so you'll need to re-copy them all to your preferred location.

Grateful plaudits to Moggy for the time he's taken to produce & report the sequences of operations that were causing him difficulties.
