Yeah... what the title says.

I mostly use the following system to store any kind of data with variable lengths to an AppVar:
first byte: number of datablocks in the AppVar
foreach datablock: one word/ two bytes: offset, relative to the start of the AppVar
foreach datablock: variable amount of bytes: the data at the position pointed to by the offset word.
but i think the most efficient way to do it when you have left over enough room in your program, to store it in your program.

I'm trying to save all of the text in my game to one string.

If you mean memory efficient, you might want to try some kind of compression by using a reduced character set. 26 uppercase, 26 lowercase, 10 numbers, a space, and a 'special character' is 64 possibilities (6 bits) which means you can store 4 characters in only 3 bytes. 'special character' (which is the binary combination 000000) would look at the next character which could be one of 64 special characters like a period, exclamation mark, parenthesis, question mark, apostrophe, and most importantly the end-of-line character. That makes all your text data about 20% smaller.
Another strategy is to chose 255 of the most used words and have a list of these "common words" to form a sentence with the unused combination representing that you will spell out the word instead. That can lead to reduction of over 50% for large text files.
Either way, you'll have to make a decoder/encoder to actually use them in your programs.

well, you could do it the way KermM does it, like described here: http://ourl.ca/7036/117479.
i prefer the way I would do it, cuz else I wouldn't have invented it :)

Hmmm, well you could store it all in one string then have a certain token that is at the beginning and end of a phrase then when a phrase is triggered it stores the number of the beginning character to whatever then use inString( to find the second one and then use sub( output the result. I don't know if that helps or even makes a lot of sense.
Oh, this is Axe. My bad :P Didn't even think to check.
