System Variable
|
_CFRAME_ is a system variable that is
provided automatically for FRAME entries. _CFRAME_ has a valid value only
when a FRAME entry's SCL code is running or when a FRAME entry or component
method is running.
Suppose the entry FIRST.FRAME contains
an icon. The icon's _select method is defined to run SECOND.FRAME, which
contains the following program:
INIT:
/* Send a method to the current FRAME */
_CFRAME_._setMsg('Running the Select method');
return;
TERM:
/* Send a method to the FRAME that */
/* contains the icon */
_FRAME_._setMsg('The Select method has finished.');
return;
When FIRST.FRAME displays and a user selects the icon,
SECOND.FRAME displays with the message "Running the Select method."
After the user ends from SECOND.FRAME, FIRST.FRAME displays the message "The
Select method has finished." This is accomplished by sending the _setMsg
method to _CFRAME_ (the FRAME entry that is currently running) in the INIT
section and by sending _setMsg to _FRAME_ (the FRAME entry that contains the
icon) in the TERM
section.
