I want to create a FUNCTION and a PROCEDURE with the same name (think MSGBOX) if you say x=MSGBOX("msg",btns) it is a FUNCTION and returns a value but you can also say MSGBOX "msg",btns and it is a PROCEDURE and does NOT return a value Normal overloading requires that the parameter signatures be different, but here there is no difference in the INPUT parameters, just the existance or lack of an OUTPUT one. Anybody got an idea ... can this be done? I was hoping for something like this FUNCTION foo(arg1 as string, arg2 as integer, arg3 as integer=0) as integer .... code return some_value END FUNCTION SUB foo(arg1 as string, arg2 as integer, arg3 as integer=0) CALL foo(arg1,arg2,arg3) END SUB EDIT a kludge Band-aid..... I made one of the arguments in the FUNCTION INT16 instead of INTEGER..... _________________ Dave Sisemore MacPro, OSX Lion 10.7.4 RB2012r1 Note : I am not interested in any solutions that involve custom Plug-ins of any kind Top charonn0 Post subject: Re: Not quite Overloading.Posted: Sun Oct 28, 2012 7:28 pm Joined: Mon Apr 02, 2007 2:08 am Posts: 946 Location: San Francisco, CA, USA You're using the Call keyword, which makes it ambiguous which method you're calling, by discarding the return value. _________________ Boredom Software Top timhare Post subject: Re: Not quite Overloading.Posted: Sun Oct 28, 2012 10:47 pm Joined: Fri Jan 06, 2006 3:21 pm Posts: 11765 Location: Portland, OR USA I do this frequently. As charonn0 says, drop the CALL keyword and everything works fine. SUB foo(arg1 as string, arg2 as integer, arg3 as integer=0) dim x as integer x = foo(arg1,arg2,arg3) END SUB Top DaveS Post subject: Re: Not quite Overloading.Posted: Sun Oct 28, 2012 11:12 pm Joined: Sun Aug 05, 2007 10:46 am Posts: 4202 Location: San Diego, CA Thanks.... _________________ Dave Sisemore MacPro, OSX Lion 10.7.4 RB2012r1 Note : I am not interested in any solutions that involve custom Plug-ins of any kind Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 4 posts ] -- Over 1500 classes with 29000 functions in one REALbasic plug-in collection.
