Call part of a .m file

Hi! Is there any way I can call just few lines of a .m file in another .m file? For instance, if there is a 500 lines .m file, how can I call the first 25 lines in another file? Or is there any way I can write a program that it goes and copy/paste the first 25 lines itself? Thanks.

Either of these options are conceivably the worst things I could imagine. The programming concept from hell.

Instead, learn to use functions. Modularize your code, into small functions. Then you can just call the part that you need.

Thanks John.

This is exactly what basic programming commands are for: if, for, switch, etc.: they control which parts of your code run, and how often. Use them.

Or, as John D'Errico suggests, learn to use functions.

Do not magically move code around and run it, unless you want to write totally unmanageable, impossible-to-maintain code.

Thank you. You are right, managed it with using 'save' and 'load' instead.

"managed it with using 'save' and 'load' instead."

How is that related to the original question? Perhaps this might be relevant:

I wanted to read defined variables from another .m file but I realised it is wrong and used save load. Thanks for your help.
