Line-To-Line
I have one string like this: Hello, I am a shopkeeper (linefeed) Thus, I like to say... (linefeed) Good Morning (linefeed) How can I put this string line-to-line recording it into a file?

How about something like this....
long ln_pos,ln_filenum,ln_start_point
string tmp_part
ln_start_point = 1
//fileopen
ln_filenum = FileOpen("c:\export.txt",LineMode!,Write!,LockWrite!,Replace!)
ln_pos = Pos(ls_your_string,'~n',1) //~r~n if CR LF
for ln_pos > 0
tmp_part = Mid(ls_your_string,ln_start_point,ln_pos)
FileWrite(filenum,tmp_part)
ln_start_point = ln_pos + 1 // + 2 if CR LF
ln_Pos = Pos(ls_your_string,'~n',ln_pos + 1) // + 2 if CR LF
next
Fileclose(ln_filenum)
Please bare in mind that the ~n is for the linefeed, if it's carriage
return in your file, you have to change the '~n' to '~r~n' , and also add 2
instead of 1 position in the code.
I wrote this code out of my head, didn't test it though... lack of time ...
( as usual ) :=)

Line by line
Hi, I have a file extremely large in size and length. I want to read the file line by line and worry about matching up each line and running that line through a subroutine instead of opening the entire file (which would take a while). So how do I open a file up and process each line individually?

Lines, what lines?
Given all the talk about high voter turnout, I got to the polls about 15 minutes after they opened at 7:15am. This was about the same time I went in 2006. The line today was about the same as then. It took about 30 minutes to vote for McCain and go. By the time I left, the line was about 30% shorter. Weather was good and parking was adequate. Are the reports of long waits just media hype?

retreiving each line, line by line in a multiline tyextbox??
I have a multi line textbox and I need to be able to retreive the data in the textbox but line by line. Meaning: that in a multiline textbox in which a user has typed text which fills up 3 lines in the textbox; I need to retreive the first line, and then the second etc.. I figure since there is a text wrap, the data inside the textbox control must contain some formating characters somewhere like a line break, or new line, or linefeed etc... How is this done please? Thanks marc Why would you want to retrive each line independly? One quick approach would be taking the whole string...

reading in a file, line by line by picking certian lines
Hi all I am looking at a way of reading a line doing a regex to find the specific line then pick out the line, sudo code would be some thing like the following: read in line check regex if regex is correct { jump 10 lines print the output } any ideas on jumping the 10 lines, how do I ignore the lines in the file, and know I'm going the right distance ?

reading line by line
Hi, I have a program that contains a pretty big block of text: my $text = <<EOF; line1 line2 .... line 120000 EOF I want to read this block of text line by line and analyse each line without needing to create a big array that contains all these lines (exactly like when reading line by line from a text file). It works fine if the program contains just a block of text, because in that case I can put the data after __DATA__ and then use while(<DATA>), but the program contains 2 blocks of text. Is there a solution for this? Thank you. Octavian On 08/09...

Name: Marco Email: marcoatxandriadotde Product: Thunderbird Summary: Lines between Lines in Mail list window instead of colouring the lines Comments: Hi, for the next Thunderbird version it would be great to have an optical change of the display of the email list.

Reading file line by line regardless of type of end-of-line?
I would like to create a perl script that reads lines from an ascii file, but that reads them regardless of whichever of the three variants (<CR>, <LF> or <CR><LF>) is actually in use as end-of-line, *without* knowing beforehand which is the case. The script should run on many systems (so installing a special version of Perl is out of the question). Now perl has the input_line_separator which you can set to a value, sadly though, it is not a regular expression.
