Re: [amibroker] Re: using say("text") (AmiBroker 4.89.0 BETA released )

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

'Say' function is designed to be doing one thing: speaking out loud user-specified text (unconditionally).

My experience shows that functions that do more than one thing and do "housekeeping" on their own
tend to be very difficult to understand by the users (see AlertIf case - it does housekeeping and 
repeatition prevention, yet no one seems to understand it). So it is better to keep rule - one function
does one thing.

  Thanks,

  I will try it later this weekend.

  This seems like a lot of housekeeping for a function that would normally be 
  required only ONCE ! (I can't envision an application that needs repeating
  unless I used it for an emergency (say("Fire") ;) 

  happy holidays

  You need to store any text to ouput in a staticvar and clear this variable after you output it, below is just one way of doing this.  
   This will only Say() text when is has changed.  
  You may have to change this when you need repetative messages, like pyramided trades that say Buy, Buy, Buy, ...


  Text = ParamStr("Enter text to synthesize","Test");
  PrevText = StaticVarGetText("PrevText");
  if( Text != PrevText ) 
  {
  Say( Text );
  StaticVarSetText("PrevText", text);
  }

  best regards,
  herman

    Thanks, I may be misunderstanding Flip but my guess is it should be the opposite,
    something like ExRem() to only sound message once on the first occurrence. 
    but I am not even sure what to include in that statement as arrays. 

        if condition say("my message");

    I would like to be said only once (the first time condition is true) and only on the last bar
    (which I will take care of after I figure out how to restrict this event).

    I haven't done this yet, but Flip function should work.

        How does one use the say("text") function such that it is only
        stated once and does not repeat even if the condition that 
        it depends on continues to be true?
