8th (FORTH dialect) pre-launch testing required

Please can folk have a look at the 8th track and tell me what’s amiss (there are holes in the documentation for example). The online editor and test-runner has been enabled thanks to @ErikSchierboom (profound indebtedness acknowledged.)

Hi Bruce,

Completed the Hello World exercise, and did a quick run-through the online environment. Looks good, works well. Hope to complete an additional exercise or two ASAP.

A magnificent effort - well done !

Thank you. Very much.
