Specify a DELETE_ operation in the upgrade file with values that match an entry of the installation file.

When you specify a DELETE_ operation, the following steps are performed:

1. A search is made of the installation file for an entry of the same type as the suffix of the DELETE_ entry type name; an entry that matches the values specified in the upgrade file entry. If no match is found, message lines are added that show the entry which could not be found.
   An example of the lines that appear when a DELETE_ operation is unsuccessful is:

   000242
   ==MSG> DELETE NOT PERFORMED. ENTRY NOT FOUND.   ICQAM907
   ==MSG> *LIBRARY          ISPPLIB           ISPF
   ==MSG> 'ICF.GONE.PLIB'
   000243

2. If the entry that is specified is found in the installation file, the entry is replaced by note lines indicating a deletion took place, and the deleted entry is echoed in note lines.
   An example of the lines that appear when a DELETE_ operation is successful is:

   000242
   =NOTE> DELETED PERFORMED. THE ENTRY DELETED WAS:    ICQAM908
   =NOTE> *LIBRARY            ISPPLIB            ISPF
   =NOTE> 'ICF.V2R2.PLIB'
   =NOTE> 'ICF.V2R1.PLIB'
   000243
