After the power is turned ON, the first screen when selecting [PROGRAM] depends on the value set in
the parameter "#1139Edtype".
"0": MDI screen
"1" or "2": Edit or MDI screen is switched automatically by the selected operation mode
To edit a machining program on the EDIT screen, use the menu key to change the screen. No
programs to be edited are called on the initial edit screen. Perform [SERCH] or [PROGRAM] operation.
To edit a program already registered in memory, perform [SERCH] operation. To register a new
program in memory, perform [PROGRAM] operation.
If the MDI screen is selected, MDI data can be entered as it is without operation such as a search.
If [EDIT MDI] screen operation is interrupted and any other function is executed, the previous screen
selected (MDI or EDIT) will appear and the previous data will be displayed by again selecting the
[EDIT MDI] screen. Then, the data input or edit operation can be continued.

The EDIT screen can be used to edit a fixed cycle program by setting 1 in parameter #1166 "fixpro".
(4) Editing macro operators
If a character string that matches a macro operator exists in the machining program (including a
comment statement), it is automatically converted into the corresponding intermediate code during
editing. This may cause a string different from that entered to be displayed during editing.
