Wow: 2^n cases for one option worded with n letters! BTW, try it:
you might discover that Ada -fortunately- is case insensitive...

Yes! Check for a To_Lower function in some Ada.* package.

BTW, the To_Upper will be more useful to compare with "BUY" "READ"
"DONE" returned by the function Menu_Options'Image( option ).

Or better: Menu_Options'Value( a_string ) will return a value
of Menu_Options type, and is case already insensitive :-) !
