Does MC-3020 optimize instance selection?
ROX has researched the selection process and provided substantial optimization in MC-3020. During the first pass of translation, selection statements are identified of the form ‘select any [inst_ref] from instances of [key_letters] where [where clause]’ when the where clause is checking for equality of the identifier. Such selection statements represent a common pattern seen in many applications. (You may see reference in the archetypes to “special where” clauses.) MC-3020 optimizes these selections for code space by consolidating the searching into subroutines. This consolidation eliminates redundancy in the generated code. In addition, these selection functions allow some embedded processors to use internal registers more efficiently, thus improving speed. (Such speed-ups have been experienced with 8051 and 80C167 family processors using Tasking brand C compilers.) For future feature enhancement and for flexibility of customization, hooks into these scanning routines are provided at
