How large is the file? And how is the file structured?

Hi Tom,
I’ve done this in the past watching it instead of the result. I seem to
remember eof was not useful. Maybe for a serial port it would be?
As in:
repeat forever

Alas, only read from socket allows a message to be sent upon completion. The
step siblings read from file, read from process and read from driver do not.
Here are a few things you might do:
1. Try making the file loading very fast and don't do it in the background.

Hey folks,

How about read for x characters, put the last line in a buffer and remove it
from the read text, process the read text, read the next block, prepend the
buffer line.

It should have been this, btw:

As far as I know you would need to use something like:

read from file tFile until tDelim

Jacque,
thanks for that code sample. I was not aware that i can use EOF in a repeat
loop as condition. I always thought that it only can be used in a read command
like
read from file MyFile until EOF
Thanks again to all who gave feedback. It helped me a lot.

Matthias

should find the first line as well:
on parseFile
put "/path/to/file" into tFile
put cr & "mstart" into tDelim
open file tFile for read
repeat until eof
read from file tFile until tDelim
-- process the text here
end repeat
end parseFile
The only hitch is t
The fact that the keyword both starts lines and is also embedded within lines
makes me believe even more that the required processing work within LC, and
not in gadgetry in the "read" command.
A keyword that starts a sentence may not have a return in front of it. That
would only occur if it starte
ntil the next line before “mstart”.

Why can you not use the
read from file tFilePath until "mstart"
of
read from {file /pathName/ | stdin} [at /start/] {until {/string/ | end
| EOF | empty} | for /amo
One thought, what if you read overlapping chunks. Like, read from 0-1, then
from 9900-2, etc. If the overlap is longer than your test string you would
still be able to pick it up, in the cases where the string spanned the chunk
boundary.
First test could be to read in 1 chunks and t
I would just read the whole file and then let LC truncate the text following
the keyword sentence in the usual ways. I bet even with a couple of
gigabytes this would not take much time.

Hi,
until today i used always put URL to read a complete file into memory. But now
i have to process really large text files with a size of 900 - 1500 MB.
I know i can read a file until EOF or so.
But how would i read a file until a line that starts with a certain keyword,
e.g. mstart. I need
