System for Efficient Program Portability,

Abstract

This technical paper describes a software system (written in COBOL 68 - X3.23-1968) designed to ease the pains of converting COBOL programs and their related data to different systems or to different software environments within the same computer system. The approach taken is novel in that two processes take place. The first process is to covert the source programs to a system independent form of COBOL. As a result of examining the source program during the source program conversion phase, the information found in the File Section is used to produce data file translation - COBOL programs which can read the data file on the old system, produce a system independent data file, read the system independent data file on the new system and convert it to a file on the new system which will take advantage of the new architecture of the hardware/software. The source program conversion processor took this into account and the converted source program will be able to process the new file with little or no modification. (Author)
