Handling correlation with blank RB
Mital Majmundar
Hello all
I have a correlation where the parameter which i need to capture is at the end of the line on which it appears.
Something like below:
&cassRegion=NA
In the above part i want to capture NA. If i dont put anything in RB (blank RB) it, obviously, captures everything till the first character encountered.
Any ideas how can i handle this?

you may need to move further beyond end the end of your data to find
one.
Take a look at the SaveLen and SaveOffset attributes to
web_reg_save_param(). Once you combine this with an ORD reference
you may be able to pull just what you need.

Hello James
I actually found a solution to this one.
Just run it with RB as " " and see wht it captures. It will capture something extra along with wht we require.
In my case it captures "NA\r". Now in the next run take the extra boundary and you got what you want.

So, you do have a right boundary, just not one which was visible, “\r”
Mital Majmundar
Yes..the right boundary which was missing is '\r'.
It actually represents a long space.
James Pulley
No, “\r” is not a long space. This is a control character for carriage return. It is often paired with “\n” as the newline character.

Yes..ok thanks James.
