Saving customized settings in a preferences file

You can place a set of commands into a data set, called a preferences file, and then indicate that file should be used by providing its name in the preferences_file suboption of the TEST run-time string. z/OS® Debugger reads these commands at initialization and sets up the session appropriately.

SET TEST ERROR;
SET DEFAULT SCROLL CSR;
SET HISTORY OFF;
SET MSGID ON;
DESCRIBE CUS;
