Bill, Would it not be better to post (copy) this message and the following postings to perl.tips oriented for beginners (like me) http://www.nntp.perl.org/group/perl.tips Later it is going to be much easier to search perl.tips with 8 messages posted up to date then go through 61314 messages in perl.beginners. Thanks, Serguei
> ATTACHMENT part 20 message/rfc822 Date: Sat, 06 Mar 2004 00:57:58 -0500 From: WC -Sx- Jones To: [EMAIL PROTECTED] Subject: HERE DOCUMENTS This is Part One of a Multipart posting - just to see if we can't keep things in the list archieves (Give the listbots something to do :) (These are not really posted questions so much as they are things that beginners need to consider.) "HERE" DOCUMENTS * Here documents are used to embed lines of text in a Perl script, for printing or variable assignment. $foo = < testing one two three $four EOT print <<_Html_; various basic html can go here sprinkled with Perl variables... _Html_ NOTE that the ending portion of a heredoc must be in column zero -- I have noticed that having indented can cause issues at times... * Variable interpolation is "on" by default. You turn it off by making it single quoted. print <<'EOP0' interpolation is off: $foo $bar are not converted to data EOP0 Whether you use Double quotes, the variables are interpolated into their corrisponding data: print < interpolation supported: $foo is related to $bar EOP1 # The following is somewhat dangerous; use with # appropriate caution - * Commands will be executed if the ending-string uses backticks. $sommand_results = <<`END_OF_COMMANDS` ls -al ps -aux END_OF_COMMANDS Also, I previously posted how to cram single lines of text into an array; it is left upto the reader as an exercise to find that posting out there in Usenet land. That's a small start to what I hope will become a long term thing :) So, if you have a statement or neat easy to understand fact about HERE Documents, post it; keep this Perl Chain Posting going... -Bill- __Sx__________________________________________ http://youve-reached-the.endoftheinternet.org/ --------------------------------- Do you Yahoo!?
