Editor.
Alternatively, you can go to the program editor using the 'Change'
pushbutton in the program name output field in the 'Event' definition.
If you are trying to access an existing program, check the spelling. You

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

Note:
You must create your form routines in a program of type 'M' (module
pool), 'S' (subroutine pool), or '1' (online program). You cannot define
your form routines in a function group (type 'F'), since the access
mechanism performed on the global data in view cluster maintenance is
not supported in this case.
Include the INCLUDE statement INCLUDE LSVCMCOD in your program to have
access to the global data in view cluster maintenance.
