Enable a function key by placing any character in the space identified by the function number. The
function key is enabled for a specific use that you determine in the RPG program. If a space is left blank,
that function is not enabled.
NOTE
The f1 key is reserved for the "command" key. The f8 key is used as the "dup" (du-
plicate) key.
Print Screen Key
Legal values for this field are Y and N.
If you enable the Print key for the current form, you determine its function. If you do not enable the Print
key for the current form, pressing the Print key causes the contents of the display screen to be printed.
The default device is LP, using the filename RSIPRINT. An asterisk (*) to the left of the Print key label
indicates that the Print key is not enabled for this form.
Retain Command Keys
Legal values for this field are Y and N.
Command keys are used in RPG programs to set indicators (KA-KN, KP-KY). When the user presses a
command key, indicators are set that the program can use to perform the desired function. The command
keys are independent of the function keys.
If Y (yes) is specified in the Retain command key specification, the command keys that were active for the
previous form are retained when this form is displayed.
If N (no) is specified, the active command keys are not kept and you can enable new command keys for this
form. Letters A through N on the Form Specification Screen correspond to command key indicators KA
through KN. Letters P through Y correspond to indicators KP through KY. Command keys are enabled for
a form by placing any character in the field corresponding to the command key. If a field is left blank, the
corresponding command key is not enabled. The command key indicators are used in the RPG program to
control the flow of operation. Refer to the HP RPG/XL Reference Manual, chapter 11 for a detailed list of
command keys.
