How to put a Char type into STDIN in JDOODLE by Pascal?

Question

I would like to ask related to JDOODLE, how can I give any parameter of char type in the STDIN window for the language Pascal? Shall I use quotations or apostrophes?

Pascal: readln(character); STDIN : c Shall I use c or 'c' or "c" ?

For all three I receive the "Runtime roor 106" (Wrong input type)

Answer 1

I guess, I figured it out: In JDOODLE the Pascal compiler can't read multiple inputs from console. I had to write the inputs in separated readln-s, that way works.
