Hi Olivier,
A couple of weeks ago you mentioned Bug 92084, which relates to the absence of information in the Help files for the OPT_BARRIER, OPT_PROB_HIT, OPT_PROB_INMONEY, and OPT_TOUCH functions.
Appendix B of the 4.1 Calc Guide contains descriptions for each of these four functions. Could that material be used to populate the missing Help pages?
Regards,
Steve
