Fill in the fields on the COBOL Debug panel as follows:

1. Enter the ISPF library or data set name that contains the input load module generated by the linkage editor. You can display a member list by omitting the member name or by using a pattern. See the "ISPF Libraries and Data Sets" topic of the z/OS ISPF User's Guide Vol I if you need help entering library or data set names, Object data sets for more information about object modules, and the Displaying Member Lists section of the "ISPF Libraries and Data Sets" topic of the z/OS ISPF User's Guide Vol I for more information about displaying member lists.
2. The Prog ID field tells ISPF the names of the sequential list data sets generated by the OS/VS COBOL compiler. You can enter up to four Prog ID names if you compiled a partitioned data set member or a sequential data set for each name. See List data sets for more information.
3. The Print ID field is optional. This field tells ISPF the name of a sequential data set to which it writes the print output from the debug session. This data set must be preallocated. See Print output data sets for more information.
4. Enter your password in the Password field if your input data set is password-protected. See Password protection for more information.
5. The Source option tells ISPF whether to allocate the list data sets specified in the Prog ID field. If you select Source, these data sets must already exist.
6. The Execution Parms field is remembered from one session to another. Therefore, you do not need to change this field unless the parameters you need are not displayed. Enter any parameters that you want ISPF to pass to the program being debugged.
7. To continue COBOL interactive debug, return to step 12.
