From The Jargon File (version 4.4.7, 29 Dec 2003) :

      Abbreviation for ?open (or left) parenthesis? ? used when necessary to
      eliminate oral ambiguity. To read aloud the LISP form (DEFUN FOO (X) (PLUS
      X 1)) one might say: ?Open defun foo, open eks close, open, plus eks one,
      close close.?

From The Free On-line Dictionary of Computing (30 December 2018) :

     1.  To prepare to read or write a file.  This
     usually involves checking whether the file already exists and that
     the user has the necessary authorisation to read or write it.
     The result of a successful open is usually some kind of
     capability (e.g. a Unix file descriptor) - a token that the
     user passes back to the system in order to access the file without
     further checks and finally to close the file.
     2.  Abbreviation for "open (or left) parenthesis" -
     used when necessary to eliminate oral ambiguity.  To read aloud
     the LISP form (DEFUN FOO (X) (PLUS X 1)) one might say: "Open
     defun foo, open eks close, open, plus eks one, close close."
      3. Non-proprietary.  An open standard is one which
     can be used without payment.
     4.  open interval.
