COBOL/400 Programming (Audio Training)

Course Description:
COBOL/400 Programming is a self-paced audio-cassette course providing comprehensive, practical training in the design and coding of COBOL/400 programs.

Time required: Approximately 15 hours

When you have completed of this course, you will be able to:
   • Use SEU and PDM to code and create COBOL/400 programs
   • Create batchable programs that print reports and process files using advanced techniques
   • Use structured programming I/O and logic control operations
   • Create and use externally described printer files with DDS and RLU
   • Use externally described physical and logical files
   • Process files using composite and partial keys
   • Use simple and multidimensional tables
   • Use sophisticated PERFORM processing
   • Pass parameters and call programs from programs
   • Execute OS/400 commands from a program
   • Use copybooks to avoid redundant code in the Working Storage Section and Procedure Division
   • Use advanced debugging techniques

Audience: COBOL Programmers
