Example from Riju:

say "Hello, world!"

Example from hello-world:

<<hello.rexx>>=
Say "Hello World"

Example from Linguist:

/* rexx */
PARSE ARG filnamn
IF filnamn='' THEN DO
   filnamn='raw'
   filnamn='font.shapes'
   end
IF ~open(fil,filnamn,r) THEN EXIT 10

CALL skriv depth,2
CALL skriv ebwidth,2
