Pete's QBASIC Site

Hello qbasic fans. First time poster, long time qbasic fan. I was wondering how to access a binary file in qbasic. I know how to with a text file, but the project I am doing needs me to access a binary file.
I know it probably sound like a lame question, but I'm stumped.

I believe you can do this with:
OPEN file$ FOR BINARY AS #1

CLOSE #1

But I don't know how to write to the file. Thought it was with POKE:

POKE p&, c
p& is the place where to poke c.
c is in the range of 0-255.

Hi supernova,

I wrote a tutorial on binary file in this webste's e-zine. You can read it here: http://www.petesqbsite.com/sections/exp ... inaryfiles

How it helps, it teaches how to write and read binary files based on datatype and also with en example using user defined types.

Hope it helps.

[quote="supernova"]access a binary file in qbasic[/quote]Sounds funny, but it is really necessary to know WHY you need to "access a binary file". Otherwise, the only answer is a general tutorial on file access including OPEN FOR RANDOM and OPEN FOR BINARY, blah-blah-blah.

What do you want to accomplish? Why?

Example: I have an EXE which has a comment that says "Do Not Copy". I want to change it to "O.K. to Copy". (or whatever it is that you are trying to accomplish).

If the answer is "nothing in particular - just wondering" then hop on MystikShadows's tutorial.

Thanks for the info guys.

Were would the MystikShadows's tutorial be Mac?

Sorry, found it, I'm an idiot.
