The parse arg may be better style, but it is fully equivalent to the three
assignment statements. Don't confuse arg foo with foo=arg(1).

Ouch! INTERPRET is unnecessary, and perhaps dangerous
because of the possibility of code injection via the value of ARG.

They probably expect you to prepare your input with CAPS ON.

Use PARSE ARG FOO BAR SOJACK, which preserves case.
