I am still a bit confused on this concept:
I guess my confusion is what defines RSTART+1 and RLENGTH-2 in this line but RSTART+20 and RLENGH-22 in the print?
In the first RSTART $5 was used as the substring, so chr15:88483984, so is RSTART+1 the chr15 and RLENGTH-2 = to :88483984? Thank you Smilie.
Hello cmccabe,

No need to be confuse Smilie

I will provide a guidance here and you could play with it. Let us assume you are printing simply RSTART and RLENGTH(RSTART will keep the index of starting point of the REGEX and RLENGTH will have the last character etc's index in it) variable's values then you will see some additional characters/digits are coming(which are not in your requirement) so this + and - to them is the adjustment of moving the cursor to print the exact required output. I hope I was clear in it, if you have doubt then kindly do let me know on same, will try to explain more on same.

Thanks,
R. Singh
