File I/O to String

[Pa|2a|)oX]

Hello,
Just wondering if there is a way to make a variable equal to the values in a text file.

i.e. A text file has the value 100101001 made from seperate variables using the put : function. I need another string variable to be equal to that value.

Thanks for any help.

read up on get .

I already have, and unfortunately it does not answer my question.

The tutorial shows how to retrieve prestored variables with the same name. I need to make a variable equal to the entire line of the file.

Thanks

Okay, so instead of assigning each line to your variable (:=) add each line to your variable (+=).
Also putting : * after your get might be useful (it gets the entire line, including spaces).

awesome, i just figured it out and came here to post results.. thanks for you help anyways


this is just an example:

code:

var num1 : int := 10 var num2 : array 1 .. 5 of int for i : 1 .. 5     num2 (i) := 1 end for var total : string var streamout : int %a var that is an int is needed to open a file var streamin : int open : streamout, "output.txt", put %this will open a connection to send data put : streamout, num1 .. for x : 1 .. 5     put : streamout, num2 (x) .. end for close : streamout open : streamin, "output.txt", get get : streamin, total : * close : streamin put total

You are only getting one line though. I thought you wanted it all? Well, this works since you've only got one line in that file, but try adding a few lines after it. See what happens? total only equals the last line. Let's fix it:

Turing:

var total := "" var temp : string var streamin : int open : streamin, "output.txt", get loop     get : streamin, temp : *     total += temp     exit when eof (streamin) end loop close : streamin put total

Dont you think the "exit when eof(streamin)" line should be over the "get :" line incase there is no first line in the data file.

Thanks, but i needed the output file for a very simple thing. One line to put, one line to get.

Its my multiplication porgram, you can check it out here:

I think errortraping the "ask" thing will make it cool, cause if i put in "qwe" it will still exit lol

Hey what happened to all my posts and submissions?

[Pa|2a|)oX]

Wow that was weird, all of a sudden almost all my posts and programs dissapeared and my post count went down from lik 12 to 6, now everything is back to normal except my posts

I will try to error trap that exit question a bit better after I'm done the other two programs, I'm just about done subtraction.
