Is there some way to create a function that will allow me to pass an unknown # of Formal Parameters like StringConcatenate()?

Specifically I get tired of typing "StringConcatenate" with 2 spaces in between each parameter. I would like to write a function "SC()" that automatically puts 2 spaces in between each parameter passed to it then calls StringConcatenate. The best I've can think of is:

string SC(string s1="",string s2="",string s3="".... string s18="")
   {
      return(StringRightTrim(StringConcatenate(s1,"  ",s2,"  ",s3.....s18)));
   }

Preferably I would like to just have the possibility of passing more than 18 parameters without having to add parameters to the function.

The number of parameters that can be passed with StringConcatenate is not unknown, it is limited to 64. I do get your point though and I think your solution is probably a good one . . just add as many parameters as you are likely to need . . .

This isn't the only utility function I have written. I expect to write more as I learn MT4. I have several hundred in my toolbox for spreadsheets and databases, so I expect that I will have a lot in MT4.

I was really hoping there was some way to simplify the parameters list.

Oh Well;
