Using ISMF

The following steps present an example of how to use the HDELETE line operator to delete a migrated data set. In our example, we have used USER20.ISMF.JCL as a sample data set name.

Generate a list of data sets as described in Methods of performing tasks.

Enter the HDELETE line operator in the line operator column next to USER20.ISMF.JCL as described in Figure 1.

The Data Set List panel appears as shown in Figure 3. The asterisk next to the HDELETE in the line operator column indicates that the deletion was successful if you specified wait for completion=Y, or that the deletion task was successfully issued to DFSMShsm if you specified wait for completion=N.
