Method and computer program stored in computer-readable medium for converting sort script to reuse jcl in different encoding environment

Abstract

The present disclosure discloses a method and a computer program stored in a computer readable medium for converting a sort script to reuse a JCL in a different encoding environment. An exemplary embodiment of the present disclosure is a sort script converting computer program to reuse a JCL in a different encoding environment, which is stored in a computer readable medium to allow a computer to perform the following steps. The steps includes: a step A of dividing one or more job steps in a job control language (JCL); a step B of extracting an executable program (PGM), a dataset name (DSN), and a data description (DD) from the job step; a step C of obtaining a file description (FD) corresponding to the data description from an executable program source corresponding to the executable program; a step D of generating a first copy book based on the file description; a step E of determining effectiveness by comparing the first copy book with the sort field included in the job step; and a step F of generating and storing a second copy book based on the first copy book in accordance with a determination result of the effectiveness.
