Basic DCL Programming
Concepts
The command-line use of DCL serves many of the daily needs of users. Repetitive or complex tasks, however, are more manageable when accomplished through DCL command procedures. Users with programming backgrounds adapt readily to writing DCL scripts. Nonprogrammers, however, can use DCL command procedures to both gain efficiency and to begin learning how to program. This module introduces the basic syntax and format for DCL procedures along with core ideas for thinking about script programming.
Objectives
  • Design a basic algorithm to solve a computing problem
  • Structure a command procedure for clarity and maintainability
  • Use basic DCL programming syntax
  • Employ symbols, logical names, and lexical functions in command procedures
Topics
  • Using an algorithmic approach
  • Designing command procedure structure
  • Writing DCL programs
  • Applying Conventions
  • Getting, storing, and changing values
  • Operators and expressions
