Cobol Advanced

Course Code

MV125

Duration

5 Days

Six months experience with COBOL and TSO/ISPF is required.

This course provides a combination of lecture, discussion and hands-on workshop in several COBOL topics. Write a program to load and read single and multi-dimensional tables. SORT a sequential file in a COBOL program using both Input and Output procedures. Write a program to accept data from the PARM field in JCL and to pass data to a subprogram. Use COBOL Intrinsic Functions such an upper case and Current Date. Write calls to the Language Environment to access system data. Debug common abends including the infamous S0C7, S013, S0C1, S0C4 with Abend Aid and / or LE Dump. Build a series of programs for a “typical” batch job scenario.

This course is designed for experienced COBOL programmers who need to become proficient in several “advanced” topics.

Upon completion of this course, participants will be able to:

  • Access single and multi-dimensional tables
  • Code the SEARCH and SEARCH ALL verbs
  • SORT a file data using the Internal SORT along with input and output procedures
  • Code COBOL Intrinsic Functions to save excessive coding
  • Call to the Language Environment
  • Pass values to a COBOL program via the JCL PARM field
  • Pass information from a COBOL main program to a COBOL sub program
  • Debug common program abends
  • Code additional COBOL Features (e.g. string, unstring)
  • Pass data from one program to another
