# STRING
"To set the key \"Foo\" to the value \"Bar\", one calls the following:

\"Bar\" \"Foo\" redis_set print cr

Notice that the value precedes the key, consistent with the idea that
a key to be fetched would immediately precede the operator doing the fetching,
and thus, the value to be set would preced _that_. So, <val> <key> <operator>
would be the natural order in a stack-based language like `dclang`.

print cr
# END STRING

"Bar" "Foo" redis_set print cr

"Now, to fetch the value we have set, we simply do:

\"Foo\" redis_get print cr
"
print cr
# END STRING

# CODE
"Foo" redis_get print cr
cr

"Next, we'll do a simlar set/get, but with the great J.S. Bach as the subject
of interest. The following is the output of two commands in succession:

\"Bach\" \"Best_composer\" redis_set print cr
\"Best_composer\" redis_get print cr
"
print cr

"Bach" "Best_composer" redis_set print cr
"Best_composer" redis_get print cr
