"chomp,chop" usage i.e. chop immediately after chomp

[martin]

Hi, I have been reading the postings on chopm and chop. I am wondering
if one would use

while <INPUTFILE>
chomp;chop;
.....
....

what is the use of this, doesn't chomp already remove the end of line
delimiter whatevere that happens to be.


Thanks, Martin

Well, sure, if for some odd reason you want to remove the last character of
the string...

what is the use of this,

Nothing particularly useful.

delimiter whatevere that happens to be.

Yeah, but chop() removes any trailing character, not just a \n.

Please do not post pseudocode, post real Perl code, with parenthesis
and curlies and whatnot.

chomp;chop;

what is the use of this,

It removes the line ending sequence if one is present, and then
removes one more character from the end of $_.

ie. it doesn't appear to be of much general use at all.

Yes. (but newline is not a "delimiter")

Then chop() does what chop() does, namely removes whatever character
is now at the end.

chomp;chop;

That only makes sense if the input file is in DOS format and being
processed on a Unix-style system. Then chomp() would remove the
"\n" and chop() would remove the "\r". There are better ways.
