Very good. In fact, great !! Thank you!

Would you be ale to do something like

constant kPiMap = { ... as above ... }


And now I'll push my luck and ponder the possibility of 'global' constants.

OK - 'global constant' is likely counter to the scope concepts. But 
perhaps they could be done as "write-once" variables, or as a more 
general "write-protected' variable.

e.g.

(somewhere in a start-up script ...)

    put 17 into gkMyMagicValue
    writeprotect "gkMyMagicValue"

and any *subsequent* attempt to change the value would fail.

Yes, coincidences do happen :-)

Thanks for the explanation Mark.
