The CRTKLIST command will create an RPG or RPGLE source member containing a key list for a keyed physical or logical file. The source code for the utility is shown in Figures 1, 2, and 3. The CRTKLIST command prompts you for a database file, a source file, a source member, and the member type.

After you run the command, the newly created source member contains the code for a key list that you can copy into your program and modify if necessary. The key list code contains one KLIST statement followed by one or more KFLD statements. The KLIST statement requires a key list name in factor 1, so the utility uses the first six characters of the record format name. For the KFLD statements, it uses the database field names in the result column.

The next time you need to create an RPG key list, try using the CRTKLIST utility. It may save you some time.
