Vim-script: How to produce an error if there is semicolon in buffer?

Hi,
using Vim 8 on Windows 7. I have written simple script that does some janitor in my config files. Tiding works fine.

I execute this script by executing keyboard shortcut: leader + r
So the following is in my vimrc file:
:nnoremap <leader>r :source $HOME\vimfiles\myscript.vim<CR>

In myscript.vim is all of the janitor work.

So far no problem. Now what I see if there is a semicolon (one or many) in my current buffer, then janitor work (executing myscript.vim) should not be performed.

How to do something like:
if semicolon-in-my-file == true
then in-status-bar-report-an-error and exit myscript.vim
else execute the rest of the myscript.vim to do the janitor work.

Thanks
