using batch files to insert signature

Win7 Home Premium x64 SP1

There is another forum where I am active that does not support custom signature options. To use a custom signature,you must have it saved somewhere else and use copy/paste to insert it into a post.

I am just beginning to learn batch files and have found that all the commands are not supported by Win7. I have no idea whether or not an elementary batch file can be written to do the following (in pseudo-code). I am guessing that the scripting is too complex for me at this stage of the learning process.

Start
Open <some_name>.txt file
Select All
Copy
Print to screen "signature ready to be pasted"
End

Then simply paste the signature instead of following the steps above one at a time to complete the task.

Before I waste too much time trying to write a batch file for this task, please tell me whether it can be done without more advanced knowledge.

Thanks.

Yes, it can be done, and easier than "selecting_all_and_copying" (those are GUI terms).
Please check my script in attachment.

If you are talking about letter C in brackets, that was a joke.

I just tried to show different commands for educational purposes.

You can do whatever you want with that script.
