-# Note: this script assumes global vars $Day,
-# $Month and $Year have been set via the CLI
-#
-# Let's get a dump of our current global variables:
-:environment print;
-
-# Let's check we can access each variable:
-:put "The day today is $Day";
-:put "The month today is $Month";
-:put "The year today is $Year";
-
-# Uh-oh...we had an issue, no values were printed!
-:put "\nThat didn't work!\n";
-
-# To access global variables declared outside our script
-# we need to declare them again within our script, but do
-# not assign a value when declaring them:
-:global Day;
-:global Month;
-:global Year
-
-# Let's try printing them again:
-:put "The day today is $Day";
-:put "The month today is $Month";
-:put "The year today is $Year";
-
-# Let's declare a new global variable to
-# access outside of this script:
-:global TimeOfDay "morning";
-:global Breakfast "muesli";
