There are numerous ways to execute Vim scripting commands. The simplest approach is to put them in a file (typically with a .vim extension) and then execute the file by :source-ing it from within a Vim session:
:source /full/path/to/the/scriptfile.vim
Alternatively, you can type scripting commands directly on the Vim command line, after the colon. For example:
:call MyBackupFunc(expand('%'), { 'all':1, 'save':'recent'})

:call ToggleSyntax()<CR>
