This information discusses how to design and write application programs that access DB2® for z/OS® (DB2), a highly flexible relational database management system (DBMS).

This paper is a mini-user guide for ICETOOL. The major features of ICETOOL for z/OS DFSORT V1R5 and DFSORT Release 14, including its JCL and control statements, are discussed at length using many examples. The objective is to show you how to use DFSORT's ICETOOL to accomplish complex tasks.

This book is a reference for Structured Query Language (SQL) for DB2 Universal Database™ for z/OS®. Unless otherwise stated, references to SQL in this book imply SQL for DB2® UDB for z/OS, and all objects described in this book are objects of DB2 UDB for z/OS.
