Abstract
A compiler for an industrial controller uses a user modifiable instruction table to contain code fragments necessary to compile particular instructions. During compilation, the instructions are replaced with the code fragments. Thus new instructions recognizable by the compiler may be added simply by editing this instruction table. Multiple instructions having the same name are resolved through a best match of operand types which examines the possible data loss in conversion of operand types to select a particular one of the instructions.
