....LDL program initializes a temporary relation which is passed to the subprogram. The results are then stored into this relation by the subprogram. The calling program can read the tuples in this temporary relation as it would any other relation. In particular, the various LDL execution models [CGK89b], such as pipelined or materialized executions, apply, as do the various compile time (local) optimizations, such as existential query optimization [RBK88] and intelligent backtracking. The following example shows how a subroutine can use these primitives to return multiple arguments. procedure ....
