RE: Chomp to trim '\r'
Why not use chop? That removes the last character. Yes, it certainly does even if the last character is not a \r character. So to do the work of one good regex substitute operator as Lee suggested you would have to determine some how (a regexp match operator?, a substring to get the last character followed by a compare to see if it was a \r, etc.). Those two distinct operations combined with a separate compare step should be evaluated as an alternative to using a single substitute operator which will remove the last character if it is there and tell you if it did or didn't remove a \r. Hmmm, which of those seems like the better alternative? Do I want my script to use four or five obtuse op codes to perform a minor function point or do I want to use just one elegant operator do accomplish the exact same minor function point? Oh. I thought all the lines ended in a \r. Sorry. R. ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

A common mis-conception among windows perl'ers is that somehow binmode is needed to properly handle a binary/non-text mode file. To the best of my knowledge, binmode isn't a Windows-only function. It's just that the most common operating systems besides windows don't make distictions between text and binary files, so it isn't useful on *nix and its variants. Apparently some older operating systems did make such a distinction (some made others as well), and it would be a necessary call on those systems. Further, I think you do need binmode to handle non-text files properly. Even sysread/read will stop reading a text-mode file when they hit the control-D character (I had this happen to me) -- you have to put the file in binary mode to continue reading past the character.

It's your way of saying to perl Thanks, but no thanks for your offer of assistance, For this file, I can handle this issue without your help. While this is true within the context of this discussion (newline conversions), binmode does other things that can also be very important. For instance, I found out several years ago that it was necessary to use binmode when opening some Word97 files in Perl scripts (under Win98), or some of the files would be truncated in the proprietary MS header. As I recall, the specific problem was a \000 byte early in the header that Perl would treat as an eof (unless binmode was in use), but I understand that binmode also turns off Perl's default handling of embedded Ctrl-Z and other control characters. So I'm not disagreeing with you, but simply pointing out that whenever the input file is in a proprietary format that mixes text with binary segments, binmode is something to think about. At least under Windows, DOS, and related OSs. And then there's the whole disciplines thing that can be done with binmode (or a 3 argument open). But I don't go there; it is my fervent hope that Perl 6.0 will fix up all that stuff before I have to deal with any multibyte unicode data. :-) -- Will Woodhull [EMAIL PROTECTED] ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

If the files that his is parsing have text data other than numbers it can get very complicated to parse CSV files. As I recall, CSV does allow commas to be included in text strings -- so first, you have to figure out where the strings are (ie, break on the '' character, then determine which are opening and closing quotes, and which may just be quotes inside a string, via escaping or duplicating), then you can figure out where the columns are. This is why I prefer tab-delimited, because I can think of _very_ few situations where a tab character is valid data. However, if he is going to use CSV, using a module which has dealt with all of the special cases may make sense. In addition, by bulding around DBI, if he suddenly needs to start getting input from some other data source, he may find it much easier to modify his code...

Multiple 'do perlscript.pl' calls
I have three questions and would really appreciate any help. 1. I am running a perl script that calls other perl scripts etc. All using the 'do perlscript.pl' method. Apparently these perl scripts have gotten so long that after a certain amount of 'do perlscript.pl' commands, the script crashes. Is there a way to extend this, and make it able to call multiple 'do perlscript.pl' calls than it currently can handle? 2. When I run Multiple 'do perlscript.pl' calls , after the third or fourth call, the error reporting seems to crap out. Is there a way to improve the error reported of multiple 'do perlscript.pl' calls? 3. How do I change directories inside of a perl script such that 'do perlscript.pl' calls(inside that same perl script) perlscript.pl inside the new directory, not the one that originally called the first perl script?

Win32::GUI crashing, burning.
Weird problem here... I've been trying to move to Win32::GUI from Tk,
and I can't even get as far as Hello World without perl crashing with
a Perl.exe generated errors and will be closed by Windows Dr. Watson
popup.
The error I'm getting happens when I try to add pretty much any widget.
For example, right now I'm trying to do something like:
my $text = Hello World;
$main-AddLabel(-text = $text);
Looking at it with the debugger, it appears that the error occurs as I'm
going through Win32::GUI::WindowProps-FETCH($self, $key), with $key =
-font. Going by the tutorials I'm reading, there ought to be a
default value, but perl crashes on FETCH returning Undef.
Even weirder, when I defined a font, it died trying to process $key =
-handle, which went through just fine before -- it doesn't even get as
far as -font.
The only thing I could think of is maybe it had something to do with the
fact that I had Cygwin's perl on this box as well, so I uninstalled
that, and reinstalled the Win32::GUI module. Still no dice.
Any ideas? Am I missing something important here?

If it is not off your system and you are getting the data from Unix, then
their end of line and the end of line for Windows are different. So when you do chomp,
chomp uses the variable $/ and what it has for doing the chomp. Otherwise if win to
win, does not make sense. Chomp works like a champ at what it does.
