Most keyboards have a group of special keys called program function (or just PF) keys. You use them for quick entry of common ISQL commands. Use of the keys is explained as you proceed through this manual. A summary of the PF keys is in Appendix C, Summary of ISQL PF Keys.
If your PF keys do not match those described in the summary, you can change their functions and tailor them to your needs. Consult the appropriate person in your organization to determine the customized key setting.
