I am getting a recurrent problem when I try to run programs where the code requests a read from a text file.

I put in:

open to read 1,"data.txt"

I then have a text file (called data) saved in the same project folder as the main source file.

But then when I run the program, it crashes and I get the error message:

File does not exist at line (whatever line number of open to read)

Sometimes programs will work, sometimes not. It seems to depend on if you have edited the text file and resaved it or something like that. Sometimes it doesnt even work with a new text file.
Is this a bug or am I doing something wrong?
I know the file does exist cos I can see it on my system.

Check that the file is in the right directory, for example if it is in a folder called 'data' the you will need to use




Make sure that if you edit it you dont change the extension, make sure that when you save it you select the .txt extension.
