Im trying to develop a program and I want the user to be able to change one variable by changing a value in a text file rather than changing it in the program. Basically all I want is for the user to be able to input a number from 1 to 99 in a text file so that the number they chose can be used as a variable in my program. Im confused by all the read file types such as "read file" and "read byte" as they all output strange numbers instead of the number in the text file when i try and use them. Any help? Thanks.

You'll need to use the READ STRING command to read the first line of text. Next use the VAL command converting the string to a numerical value.

Computers work in that way. When you type "255" in a Notepad file, it isn't storing that as the number 255, it stores it as the number 2, followed by two 5's.

There is a command, "write string" that'll ouput and input readable text. Read byte and such commands are a way to save numbers all together, and not as a series of digits.

So your code would look like this:



That's all there is to it.

You could always save an array rather than using the open to write and read commands. I find that command quite effective and even easier than open to read/write.

He isn't saving, he's reading from the file. That's the only way I know of to do that.
