NWMF2001 TSO/E CLIST Programming
DESCRIPTION
This 5 day course will introduce students to the skills necessary to
code TSO/E CLISTs.
AUDIENCE
Programmer, technical support personnel, and other individuals
that need to write CLISTs.
OBJECTIVES
Upon successful completion of this course the student will
learn to:

- Access the terminal for user input and
CLIST output.
- Perform arithmetic calculations and
character operations.
- Use such CLIST programming constructs
as:
- IF statements.

- Use CLIST control variables and built in
functions.
- Use CLIST facilities to debug their
CLISTs.
- Issue TSO commands from a CLIST.
- Execute programs from CLISTs.
- Perform sequential file I/O.
- Nest symbolic variables to create CLIST
arrays.
