[mercury-users] carriage return escaping

[Michael Day]

Hi,

Can anyone explain why the output of the program below is:

"\n"
'\015'

on my system rather than:

"\015"
'\015'

or:

"\r"
'\r'

?

'\r' seems to be converted into the number 13 in the generated C code,
which seems correct. "\r" is getting converted to ^M, not sure exactly
what that is in this case.

Michael


:- module return.

:- interface.

:- import_module io.

:- pred main(io__state, io__state).
:- mode main(di, uo) is det.

:- implementation.

:- import_module char, string.

main -->
    write("\r"), nl,
    write('\r'), nl.
