Sample text

CUSTOMER*D-(CUSTNAME =WALLS, HOOPER J. CHCKACCT CHCKDEBT(DEBTDATE =030594) ) The PCB mask data will contain CHCKDEBT as the name of the last segment successfully retrieved, and the key feedback data contains the concatenated key fields of the CUSTOMER and CHCKACCT segments. The CHCKDEBT segment has only a search field and no sequence field, and therefore no data for CHCKDEBT is in the key feedback area. IMS Execution Modes When the SAS/ACCESS interface to IMS accesses DL/I databases, it executes within a DL/I subsystem.

See “Invoking the ACCESS Procedure” on page 100 for complete reference information about these statements. JCL statements; included for batch and noninteractive line modes. libname mylib=’access-descriptor libref’; libname vlib=’view-descriptor libref’; reference the SAS data library in which you will store the access descriptor (MYLIB) and the SAS data library in which you will store the view descriptors (VLIB). You must associate a libref with its data library before you can use it in another SAS statement or procedure.

An unqualified SSA has the form segment-name < command code> where segment-name is an 8-byte field specifying the segment type, followed by a blank. A blank follows because the minimum SSA length for a DL/I call is 9 bytes. Command codes consist of an asterisk (*) followed by a letter, such as *U or *D. * The IMS DATA step programs can return PCB mask data to the user, but the SAS/ACCESS engine interface cannot. IMS Essentials Segment Search Arguments 29 If an SSA provides a field name and specific value for that field, it is a qualified SSA.
