does Readline() grab a row of text from the open file ? If so.. then that's the problem.. the problem is the fetch cost off the device, to counter this, load the file as a binary blob into a mem block then decode it once it's in memory.

Yes, Readline pulls off the top line, and I think if it is called again it pulls off the second line, third line etc.


Any example you could provide? Or rough outline ?

do you need to load/open it every time? can't you just leave it open?
so load/open it at the start of your code and then in your function just read the desired line(s)

What actually happens when you try to load it? Does your game crash, or does it just take a really long time?

Maybe you could load it in chunks. Like split the file up into 4 or 5 smaller files and load those.

oops, I found my mistake.

I put - CreateMemblockFromFile( 4444, "200K words." )

instead of -

CreateMemblockFromFile( 4444, "200K words.txt" )

Do you see the difference? I left out .txt

(I left out the '.txt.) and the AppGameKit gave me no error message about it

Assuming Readline() is able to long lines, then if you pre-process your dictionary and replace all the EOF's characters (10 & 11) with some other ASCII symbol in notepad. So you'd replace the 10's and 13's with say the pipe character | doesn't matter what it is as long as it's not naturally present in the file. Once you'd done this, you should then be able to load the whole line into a single string, then cut it up with the string functions. Which is easier than mem blocks, but it depends on the what is going to used for. If you'rre going to search / sort this stuff, then a custom structure is probably the best bet to avoid the string function overhead.
