Why take this course?
After completing this course, you will be able to
- Describe the TSO environment, and describe the distinctions between TSO commands and REXX instructions
- Write REXX EXECs to accomplish useful functions
- Use TSO commands to work with datasets, either in native mode or in EXECs
- Use REXX instructions to work with records in files
- Use subroutines as a coding technique for EXECs
- Use TSO and EXECs to run programs in the Foreground or the Background (batch)
- Run EXEC's in the batch, in TSO/E-integrated address spaces or non-TSO/E-integrated address spaces
- Use TSO commands to send and receive datasets between users
- Use the REXX compiler, if it is available
- Use the level 2 REXX constructs, if they are available.
