SET USER-COMMAND f.
This statement only works with lists.
Sets the contents of the field
f as USER-COMMAND
and executes them immediately when the list is next displayed (i.e. the system suppresses the list display
und immediately processes the event AT
LINE-SELECTION, AT
USER-COMMAND or, in the case of a system function code (list of reserved function codes,
see AT USER-COMMAND),
this system function).
The effect is exactly as if the user had entered the function in the command
field and pressed ENTER. This means that
the current positioning of the list (SCROLL)
and the cursor (SET CURSOR) is taken into account.
You can specify SET USER-COMMAND several times in the
same event.
If you set several functions one after the other with USER-COMMAND
when creating a list, only the last one is effective.
If the function key ENTER in the GUI
status of the relevant list itself contains a function code, this is executed rather than that specified with SET USER-COMMAND.
You can also use this key word with asynchronous RFCs (
CALL FUNCTION func STARTING NEW TASK taskname) by
using the addition PERFORMING form ON END OF TASK. Here,
the key word SET USER-COMMAND is used in the subroutine (see RECEIVE).
Process a line selection immediately:
WRITE: 'List'... "Create a list
SET CURSOR LINE 7.
SET USER-COMMAND 'PICK'.
The event AT LINE-SELECTION is processed immediately for list line 7.
Process a function immediately:
WRITE: 'List'... "Create a list
SET USER-COMMAND 'FUN'.
Processes the event AT USER-COMMAND immediately; the system
field SY-UCOMM contains the function code FUN.
Leave list immediately:
WRITE: 'List'... "Create a list
SET USER-COMMAND 'BACK'.
The list is not displayed, but is left immediately.
Create list with dialog box 'Find by...':
WRITE: 'List'... "Create a list
SET USER-COMMAND '%SC'.
The list is displayed with the dialog box 'Find by...'.
