// SixtyPical 0.11 introduced a new syntax for defining routines
// (routine was made into a type, and you can now say: define name type.)

typedef routine
  inputs x
  outputs x
  trashes z, n
    routine_type

vector routine_type vec

define foo routine_type
{
  inc x
}

define main routine
  outputs vec
  trashes a, z, n
{
    copy foo, vec
}
