Defining Panels

When you define a panel it requires two steps:
  1. You must first use an editor to create the panel source file in the REXX File System. The panel source should contain field control characters and the panel layout. The panel layout may contain field control characters along with regular displayable text characters, and possibly, imbedded variable names.
  2. Then you convert the panel source into an intermediate form (panel object) that can be used by the panel input/output commands. The panel facility automatically generates the intermediate file when the input/output command that is referencing that panel is first invoked or an explicit command within the REXX environment (or a REXX exec containing the command) can be invoked to generate the intermediate file.
    Note: This automatic generation is executed whenever the panel object cannot be found or when the panel source has a date or time change that is later than the panel object. Any change to the panel source causes a new panel object to be created. Therefore, be cautious when you change a panel source after a program using that panel is out of the testing phase. It is to your advantage to move the panel source out of the RFS or into an RFS directory not accessible by the program after the project goes into production.
