Relogix is an advanced software conversion tool which can port mainframe assembly-language source files, automatically re-coding them into naturally-structured, readable, maintainable C, complete with meaningful variable names and types.
Unlike most other attempts at automated migration from assembler to C, Relogix produces results close to what a skilled human programmer would produce if asked to re-write an assembler source file in C - only with fewer bugs and in a very much shorter time.
