That\'s because, the commas will be replaced by spaces inside the alias. Put an \'echo -a $1-\' on the 2nd line of the alias to see what I mean.

Why use commas? When you separate anything with a comma in the alias like the sample usage, mIRC treats each separated token as a parameter meaning the first token will be $1, 2nd will be $2 and so on, kinda like what /tokenize does.

Sample:

1. If you still have the echo there, leave it.
2. then do

//echo -a $standev(1,2,3,4,5)

and it should give you the same numbers separated by a space.

1. then now change $1- to $1 in echo inside the alias
2. now do the same echo again in #2 & it would only give you \"1\"
3. Now use the same echo BUT change the comma to a space & it should give you all the numbers.

See the difference?
