012 and 015 eq \r and\n on what conversion chart?

[Trina Espinoza]

tr/\012\015//d;

So a while back ago, there was someone kind enough to pass me the above snippet of code, which removes returns
and newlines from data attained by perl. It works great and I would like to find the conversion table that was used
so I can obtain the numbers to rid my code of other annoying characters ..

When I looked it up on the ascii conversion chart it said that the decimal equilvelent for 012 and 015 are ^J ^j LF lf linefeed c-J c-j \n and ^O ^o SI c-O c-o shift-in.

Can someone tell me what 012 and 015 represent if not \r and \n? Should I be looking at another type of conversion table?







Thanks!

Hi -

Numeric literals beginning with '0' are OCTAL:

\012 == 000 001 010 == 0x0a == decimal 10.

According to ASCII, 015 is the carriage return character and 012 is the
line feed character. The \r and \n escape sequences represent carriage
return and line feed within perl itself but \n may be represented
differently in files depending on the OS and file system.
