Example from hello-world:

PROGRAM Hello
#USE ioconv

SEQ
  write.full.string(screen,"Hello World")

Example from the Hello World Collection:

PROGRAM Hello
-- Hello world in Occam
#USE ioconv

SEQ
  write.full.string(screen,"Hello World!")

Example from Wikipedia:

ALT
   count1 < 100 & c1 ? data
     SEQ
       count1 := count1 + 1
       merged ! data
   count2 < 100 & c2 ? data
     SEQ
       count2 := count2 + 1
       merged ! data
   status ? request
     SEQ
       out ! count1
       out ! count2
