Hi vgersh99,

I'm just going through this post and having trouble understanding the code. Could you please explain the rindex function for me? I'm still learning..

Quote:
function rindex(str,c)
{
return match(str,"\\" c "[^" c "]*$")? RSTART : 0
}
Also, why did you use rindex function and not the following. I'm just curious to know and want to improve the way I look at problems.

Code:
idx=substr($4, 2, 17)

Thanks in advance!
