On Unix there is a utility called dos2unix (IIRC) that can convert DOS text to Unix text, if not then s/he can use the tr program: tr -d '\015' < sample.pl > newsample.pl On the Windows side you could use a programming editor (like UltraEdit) that can save files in the Unix text format. AFAIK Perl can run files on Windows in this format. John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It is probably your email client that is causing the problem. I used Wordpad for over a year and never had the problem, except once when I posted some code on my web site for unix users to download. It was the web that added the CR's. Bompa -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Illegal character error for blank line.
In Unix, the person has to do two things 1./ On the very first line of the file, he/she has to insert the location of his/her PERL interpreter (the location of the PERL interpreter can be found with "which PERL"). For example; redhat1:/home/(38)% which perl /opt/local/bin/perl <-- system's response So, in my case, I will insert #!/opt/local/bin/perl On the first line of the file. 2./ Remove ^M from the end of every line. This could be done by running "dos2unix" on the file, or by simply using "search and replace" in a Unix-based editor. I normally use vi, and then in command mode enter: :1,$s/^M// where ^M is created by pressing Ctrl-v followed by Ctrl-m (v and m are lower case letters). __ William Ampeh (x3939) Federal Reserve Board __ William Ampeh (x3939) Federal Reserve Board -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

A simpler way with Perl:
perl -pi -e 's/\cM//g'

Re: Illegal character error for blank line.
You've run across the typical cross-platform issues that arise between Unix
and Windows. The problem is that Windows uses \r\n to terminate a line
while Unix just uses \n. When perl on unix sees \r it doesn't know what to
do because it only expects \n. Therefore, to correct the problem, you need
to change all \r\n to just \n. A typical way to do this is to run dos2unix
on the file. However, not all systems come with dos2unix. Therefore, you
can run
perl -e "while( <> ) { s/\r\n/\n/g; print; }" infile.txt > outfile.txt
and have it remove the extraneous \r characters from infile.txt and have it
written to outfile.txt
Thanks!
