SAS/ACCESS Interface to IMS-DL/I Software

Introduction

The SAS/ACCESS interface to IMS-DL/I enables you to browse and update your IMS-DL/I data directly from a SAS session or program. This chapter shows you how to use SAS procedures to review and update IMS-DL/I data that is described by SAS/ACCESS view descriptors. The examples in this chapter use the view descriptors VLIB.CUSTINFO and VLIB.CHCKACCT. See Appendix 2 for definitions of all the view descriptors referenced in this chapter. Appendix 2 also includes the IMS-DL/I database and SAS data files and data sets.

To browse or update IMS-DL/I data, you must use a Program Specification Block (PSB) that contains a Program Communication Block (PCB) with the level of access desired. You need to have this desired level of access to the database, to the segments in that database, and to the fields in those segments. The types of access that a PCB can allow include

G get

I insert

R replace

D delete

A all

Refer to Understanding IMS-DL/I Essentials and Program Specification Block for more information on accessing IMS-DL/I data.

READ, WRITE, ALTER, or PW passwords can be assigned to a view descriptor, access descriptor, PROC SQL view, DATA step view, or SAS data file. See ACCESS Procedure Reference and SAS System Passwords for SAS/ACCESS Descriptors for more information on assigning passwords.
