The CICS TS - Preprocessor, Conversations and File Control course discusses the use of CICS commands in COBOL and PL/I programs and explains the differences between various conversational processing modes. Information describing how CICS accesses data from Direct and Sequential files is also provided.
Programmers who require knowledge about application programming in the CICS environment and the Command Level Programming Interface.
Knowledge of basic coding in COBOL, PL/1, or Assembler.
After completing this course, the student will be able to:
- Identify CICS command syntax particularly in COBOL and PL/I programs
- Recognize the facilities available through the CICS Command Level Programming Interface to efficiently achieve all the standard online terminal network functions
- Identify how CICS functions are developed by using pseudo-conversational programming techniques
- Identify how CICS access Direct and Sequential Files
