Removing trailing spaces in eScript

At the moment in Siebel, there is no trim function in eScript available to remove leading spacing in a string. In Vbscript, this function is available but not in eScript. A change request has been created to add this function to eScript.
After searching in supportweb, i came acros a piece of code provided by Siebel to replace the Ltrim() function. The code looked like this:

function trim(source)
{
var beginOfString = 0;
var endOfString = 0;

for(var index = 0; index < source.length; index++)
{
if(source.charAt(index) != " ")
if(beginOfString == 0)
beginOfString = index;
else
endOfString = index;
}

return(source.substring(beginOfString, endOfString + 1));
}

At first, it looked like the code did what it had to do, remove trailing spaces. But then I noticed that when there are no leading spaces, the code also removes the first letter in the string. Since this is unacceptable, I tried to wrote my own code and it turned out to be very simple.

My code looks like this:

function trim(source)
{
while(source.charAt(0) == ” “)
{
source = source.substring(1);
}
return(source);
}

Just a few lines of code but it does the work without removing letters if they are not spaces. Feel free to use the code whenever you need it.
