You can display and accept configuration variables within the debugger. To display a particular variable use the following command:
d %var-name
where var-name is the name of the variable you want to display. Up to 300 characters of the value are displayed. (This is equivalent to executing the ACCEPT FROM ENVIRONMENT command, and can show the same types of configuration variables.)
To accept a configuration variable, execute the command:
a %var-name
where var-name is the name of the variable you want to modify. In this case, the debugger responds with a prompt. Enter the new value of the variable, ACCEPT that variable within the COBOL program, and the runtime will use the new value.
