Hello
I would like to know how to delete a character from a string knowing that I have a loop that looks for a comma in the last character and deletes it.
example
string = a,b,c,d,e,f,,,,,,,
it becomes
new_string = a,b,c,d,e,f
when the loop finds that there is no comma in the last character, it stops
(input is not a multigroup, it's just a chekbox)
thank you very much

I'm not sure if you're really posting about CSPro, but if so, you can do something like:

function string RemoveTrailingCommas(string text)

    // convert commas to spaces

    do numeric ctr = length(strip(text)) while ctr >= 1 and text[ctr:1] = ',' by -1

        text[ctr:1] = ' ';

    enddo;

    // return the trimmed string (to remove the added spaces)

    exit strip(text);

end;
