Assemblers won't assemble!!

[Queatrix]

I have tried to assemble the following code in TASM and Flat Assembler, but they both give an error for every line of code. What is going on? How can I get the assemblers to assemble the * code?? Thanks for any help you can provide.

You have failed to use the proper directives to organize your code and data. Please read TASM's documentation.

I should note also that you've got some pretty egregious errors there, particularly when calling and not returning.

Hope this helps.

I see, after really looking through it, I got rid of some errors, and it took care of the rest.
