Insert a line into text file

| This is really annoying me. Should be simple. Basically, I'm trying to insert a line to a test file...
myfile:TStream=WriteStream("test.txt")
If WriteLine(myfile,"Hello") Print "Hello successful!"
If WriteLine(myfile,"World") Print "World successful!"
CloseStream(myfile)
myfile1:TStream=OpenStream("test.txt")
ReadLine(myfile1)
If WriteLine(myfile1,"AGAIN") Print "AGAIN successful"
CloseStream(myfile1)
myfile2:TStream=ReadStream("test.txt")
While Not Eof(myfile2)
Print ReadLine(myfile2)
Wend
CloseStream(myfile2)
<edit> P.s. tried simple writefile/openfile/readfile. I just can't get Openstream/file to read and write. Seems to only allow one of them. |

| Tonyg, Have you tried looking at the seekstream, streampos functions? |

| I have, and I have just found one of my own posts suggesting it to somebody else. I may well be trying to forget about this post in a few minutes but I still won't know why I need to seekstream. <edit> Hmmm, it's still a case of inserting a line. My guess is I will have to read and write each line. Maybe I did consider seekstream. It will only allow me to write to a certain position in the file. However, if that position is occupied it will overwrte that line. Without rewriting the while file I can't see how to insert. (which makes sense of course). |
