replay a vim macro until end of buffer

Question

I want to run a macro I just recorded in register \"x\" on every single line of an open buffer, from my cursor to end of the buffer, in vim. How do I do that?

Answer 1

make recursive macro:

qa@aq

ex:

qa0gUwj@aq

It'll UPCASE first word from current line to the end of file with single @a. But make sure "a register is empty:

let @a=""
