/* FUNCTION: CMP * 00020000

/******************* Modifications ****************** 00110001
/* 08/31/92 By: David Leigh * 00090001
/* I added a call to UTILLOG at the * 00090001
/* beginning and I added code to allow * 00090001
/* people with no TSO PROFILE PREFIX to * 00090001
/* use CMP. I looked into changing each * 00090001
/* dataset reference to use an explicit * 00090001
/* SYSUID prefix, but that looked more * 00090001
/* complex at first glance than I wanted to* 00090001
/* get. The problem with this method is * 00090001
/* that if CMP bombs and the prefix had * 00090001
/* been changed just for CMP, it would * 00090001
/* remain changed and the person would be * 00090001
/* screwed up! * 00090001
/* 06/19/95 By: David Leigh * 00090001
/* In the event of an IEBUPDTE bad return * 00090001
/* code CMP will now edit the SYSPRINT * 00090001
/* dataset and then exit the CLIST. This * 00090001
/* was added to both IEBUPDTE calls. * 00090001

Documentation
CMP COMPARES TWO VERSIONS OF A PROGRAM AND CREATES A MERGED VERSION OF THESE PROGRAMS. IN ORDER TO ACCOMPLISH THIS, A COMMON BASE VERSION MUST EXIST. AN EXAMPLE IS P@USER1 AND P@USER2 MADE CHANGES TO PROGRAM COBOL1. THE COMMON BASE VERSION OF COBOL1 IS STORED IN SLSS.PRD.COBOL2(COBOL1). EACH USER HAS THEIR VERSION STORED IN P@USER?.SLSS.COBOL(COBOL1). CMP WILL COMPARE EACH P@USER1 AND P@USER2 VERSIONS TO SLSS.PRD AND CREATE A MERGED VERSION IN A DATASET CALLED P [at] USER1 [dot] CMP [dot] UPDATED(COBOL1). IF YOU HAVE ANY PROBLEMS WITH THIS FEEL FREE TO STOP BY AND ASK QUESTIONS. JIM X352
