Incremental programming environments are becoming increasingly popular. Earlier systems are mostly based on interpretation. DICE is an incremental programming environment based on incremental compilation only. In this thesis the retargeting of the code generator from PDP-11 to DEC-20 is described. DICE supports separate host and target environments. The code and data administration in the target is discussed and analyzed. A new runtime environment in the target is created by providing an interface to an existing one. In DICE, the traditional compile, link and load passes are integrated and interleaved. A classification of linking programs is made from this point of view.
