Using full-screen mode: overview
Note: This chapter is not applicable to IBM® Developer z/OS® (non-Enterprise Edition) or IBM Z and Cloud Modernization Stack (Wazi Code).
The topics below describe the z/OS Debugger full-screen interface, and how to use this interface to perform common debugging tasks.
Debugging your programs in full-screen mode is the easiest way to learn how to use z/OS Debugger, even if you plan to use batch or line modes later.
The following list describes the maximum screen size supported by z/OS Debugger for a particular type of terminal:
- In full screen mode, you can use any screen size supported by ISPF.
- In full-screen mode using the Terminal Interface Manager or a CICS® terminal, you can use a maximum screen size (number of rows times number of columns) of 10922. If the number of rows times the number of columns is not less than 10923, z/OS Debugger displays a WTO error message and abends.
