Use the CORE=Bkpt Menu screen to display or change storage relating to the task currently stopped at a breakpoint. All fields, except the numbered ones, operate the same as for the CORE=Bkpt menu displayed for a COBOL program stopped at a breakpoint.

To display the contents of a register, a program location, or a data location, perform the following steps:

1. Make the appropriate entries in fields Œ, , and Ž as described next.
2. To display the program code at a particular location, enter its label in field .
3. To display the contents of a data field, specify its location by entering the name of the base register in field Œ, and its displacement (from the address in the base register) in field .
4. To display the contents of register n (a decimal number from 0 to 15), enter the desired register number in field Ž.
5. To display an argument on your program's Argument List, enter a decimal number from 0 to 99 in field .
