Structured COBOL Workshop

Recommended Duration:
5 Days
COBOL for OS/390 and VM
Also appropriate for shops running COBOL for MVS & VM, COBOL/370, VS COBOL II, COBOL for VSE, or any ANSI 85 COBOL.
Students who complete this course will be able to write or maintain COBOL programs that do not require advanced capabilities of the language. The emphasis here is learning the basics of the language, along with developing program design skills using pseudocode. All lectures and exercises support the ANSI '85 standard. For the IBM mainframe environment, this means the VS COBOL II, COBOL/370, COBOL for MVS and VM, COBOL for OS/390 & VM, and IBM COBOL for VSE compilers.
Experienced programmers needing to learn COBOL as an additional language. (this course is also suitable to provide a first programming language)
The student entering this course should have 3 months recent experience using ISPF/PDF especially the text editor and should be able to code JCL to run simple batch jobs or have completed an "Introduction to TSO/ISPF" and "MVS and OS/390 JCL and Utilities" courses within the last 12 months. Some introduction to data processing concepts is also recommended. 
Major Topics
  • The COBOL Language
  • ANSI Standards
  • EBCDIC / ASCII Coding Schemes
  • Data Descriptions
  • Sequential Files
  • Major COBOL Verbs
  • Pseudocode and Program Design
  • Working with Print Files
  • Intrinsic Functions
  • Using File Status
  • COPY Statement
There are 17 machine exercises. Exercises can run on any platform that provides a compiler that supports the ANSI '85 COBOL standard; the class also supports the 1989 addendum to the COBOL '85 standard, which introduced intrinsic functions. (COBOL for OS/390 & VM, COBOL for MVS and VM; COBOL for VSE; COBOL for OS/2; IBM COBOL for AIX; all but intrinsic functions are supported by VS COBOL II (R3 or later) in MVS, VM, and VSE; Micro Focus COBOL dialects that support this standard may also be used.
