On successful completion of this course, the student, with the aid of the appropriate reference materials, should be able to:

1. Code application programs in Assembler, COBOL, PL/I, or C, that run under TSO and that can
   • Accept and use parm data
   • Set normal and abnormal return / completion codes
   • Issue TSO commands (using IKJEFTSR)
   • Access, modify, create, and delete REXX variables (using IKJCT441 and IRXEXCOM)
   • Work with data in DB2 data bases
2. Use TSO and REXX EXECs to run programs in the Foreground or the Background (batch)
3. Run EXEC’s in the batch, in TSO/E-integrated address spaces (IKJEFT01) or non-TSO/E-integrated address spaces (IRXJCL)
4. Code programs in Assembler, COBOL, PL/I, or C that can be invoked using the TSO REXX facilities for LINK and ATTACH (address link, address attach, address linkmvs, address attchmvs, address linkpgm, address attchpgm), accepting parm data in the multiple various formats provided by these alternatives.
