How to give CRLF (carriage return line feed) in Appian. Eg:- "ABC"

char(10) or char(13) doesn't seem to work.

I tried the following:
="ABC" & char(13) & "XYZ"
It returned me simple ABC XYZ instead of
ABC
XYZ

Are you using this in a SAIL form, or in the forms designer?

I wanted to use in both the places.
Currently, I am calling this from within a rule.
Please provide your inputs.

I ran a quick test with using char(10) and char(13) in paragraph fields in both SAIL and forms designer, and can confirm that it works in both those situations. I tried by hardcoding the string, as well as using a rule as a reference, and it worked in every case. The only place it did not work was directly in the expressions editor. Is that where you've tested so far?

Yes.
Could you please sent me that piece of code.

It's the same as the one you posted above.

Hi,
I defined 2 variables and used the following function:
=firstInput & char(10) & secondInput
It did not return CRLF.

It works for me when using rule inputs. I defined
ri!one & char(13) & ri!two
Where both rule inputs are text. I then used this rule as the value for a paragraph field, passed in a couple strings, and it displayed the CRLF properly
