The p3270keys keyboard mapping file translates a set of keystrokes generated from the terminal of a target system into the function key structure the IT and the generated applications use.
This translation is done when the AEF obtains ASCII terminal input and output string definitions from the p3270keys file that contains input key-to-function definitions to associate a character string received from the keyboard with a particular 3270 control or function key. The AEF also uses the p3270keys file definitions to determine the character string to output to the terminal to execute a particular screen function.
The IT includes a standard p3270keys definition file with all the elements required to describe a particular terminal environment operation, such as function key definitions, color commands, and screen display descriptions. The IT install places the p3270keys file in the $IEFH directory as a text file that can be edited to add new key mapping or changed to reflect different functions for existing terminal types.
