BEFORE-CLOSE and CLOSE — Technically, p_other should be unknown (?) after a file closes; however, this parameter still shows the last available file name for the procedure file. Unknown (?) appears only if there is no filename.
BEFORE-RUN, RUN, BEFORE-DEBUG, DEBUG, BEFORE-CHECK-SYNTAX, and CHECK-SYNTAX — These all use the last specified filename as p_other. The actual file being run or checked is a temporary file with a name like p01928384.ped. This name is not used.
If the user tries to close a buffer, then the Procedure Editor first prompts the user to save. The entire save operation events fire before the call to BEFORE-CLOSE.
NEW is called after a buffer is created. You see the buffer before the NEW event is called. All events are called after the event has finished.
When you control the handle for the Procedure Editor window, you can manipulate the display of the window. For example, you can add a menu option.
