Dos/vse JCL

This book starts by explaining the basics of VSE...what it is and how it works...and describes some software products that aren't part of VSE but are used all the time...like the spooling program, Power, and the interactive editor, ICCF. Then, it teaches you how to: compile and execute application programs; handle tape, SAM, DAM, ISAM, and VSAM files; maintain VSE libraries and sublibraries; code Power statements (JECL) to manage job scheduling and output processing; write and use procedures (that includes coverage of conditional JCL, symbolic parameters, and nested procedures); and run common system utilities.
