case
CASE value clauses (library procedure)
command or operation. The second input is a list of lists (clauses);
each clause is a list whose first element is either a list of values
or the word ELSE and whose butfirst is a Logo expression or
instruction. CASE examines the clauses in order. If a clause begins
with the word ELSE (upper or lower case), then the butfirst of that
clause is evaluated and CASE outputs its value, if any. If the first
input to CASE is a member of the first element of a clause, then the
butfirst of that clause is evaluated and CASE outputs its value, if
any. If neither of these conditions is met, then CASE goes on to the
next clause. If no clause is satisfied, CASE does nothing. Example:
to vowelp :letter
output case :letter [ [[a e i o u] "true] [else "false] ]
