C414 z/OS Assembler Programming Part 2: Interfaces

Course Code: C-414
Recommended Duration: 3 Days

Benefits

Students who complete this course will be able to write or maintain Assembler programs that: process or create variable length records; involve subroutine linkages; use dynamic serial linkages such as LINK, LOAD, DELETE, XCTL; use other system service routines.Students will also gain a solid basis for debugging and dump reading Assembler programs.

Audience

Experienced or beginning Assembler programmers needing to learn additional support, design, debugging, or maintenance skills.

Prerequisites

This course is intended as a follow-on to course C410.
