I guess that would be a good solution - my only problem is that the
file has 5.6 Gigabytes. So I can't put it all in memory.
My real problem is here:
put 1 into vStartwert
set the cursor to watch
open file tFileIn
open file tFileOut
repeat forever
read from file tFileIn at vStartwert for 1000000 lines
put it into vChunk
replace ";" with tab in vChunk
replace "," with "." in vChunk
write vChunk to file vFileOut at end
add number of chars of vChunk to vStartwert
end repeat
close file tFileIn
close file tFileOut
This works until the output file reaches 2 Gigabytes. So I think
vStartwert is getting to big and doesn't work anymore. Therefore I
wanted to delete
the Lines I already treated in the input file so I could always start
at the first line.
Maybe there is a better solution?

Hi all
is there a way to delete lines in a text file from Revoution? - i
did not see how this can be done but probably it is very simple.
Till,
You have to read it in then write it back out. You can do it in one
line like this (assume you want to delete the first line):
put line 2 to -1 of url "file:/path/to/file.txt" into url "file:/
path/to/file.txt"
Just modify the range of lines you want to have in the final file.
