The Free On-line Dictionary of Computing (19 January 2023):

virgule

    Rare, and ambiguous: slash or comma.

   "Virgule" (or rather, Latin "virgula", meaning "little rod"
   or, vividly enough, "little penis") was the name of a
   punctuation character shaped like a small slash and used in
   the Latin writing system much like a modern comma -- hence
   the ambiguity of this term in modern English.

   Compare French "virgule" and Italian "virgola", meaning
   "comma" (not "slash"); Italian "doppia virgola" and
   "virgoletta", both meaning "double quote".
