Abstract: A system, method and computer program for rehosting a legacy application computer program written in one computer program dialect to a target dialect, for porting a control computer program, such as a Test Program, from one hardware platform to another, and for analyzing a computer program and creating a report. The rehost computer program is used to create a translation module in a first dialect which is comprised of a plurality of processed statements that are parsed, formatted and generalized and to store the statements in a searchable tree format. An existing translation module is enhanced by processing a number of programs and adding only unique statements. Each statement in the existing translation module has as a nested array an equivalence in the target language.
