:[range]so[urce] Read Ex commands from the [range] of lines in the
current buffer. When sourcing commands from the
current buffer, the same script-ID |<SID>| is used
even if the buffer is sourced multiple times. If a
buffer is sourced more than once, then the functions
in the buffer are redefined again.
Sourcing a buffer with a Vim9 script more than once
works like |vim9-reload|.
To source a script in the Vim9 context, the |:vim9cmd|

:[range]so[urce] [++clear]
Read Ex commands from the [range] of lines in the
current buffer.
When sourcing commands from the current buffer, the
same script-ID |<SID>| is used even if the buffer is
sourced multiple times. If a buffer is sourced more
than once, then the functions in the buffer are
defined again.
To source a range of lines that doesn't start with the
|:vim9script| command in Vim9 script context, the
|:vim9cmd| modifier can be used.
When a range of lines in a buffer is sourced in the
Vim9 script context, the previously defined
script-local variables and functions are not cleared.
This works like the range started with the
":vim9script noclear" command. The "++clear" argument
can be used to clear the script-local variables and
functions before sourcing the script. This works like
the range started with the |:vimscript| command
without the "noclear" argument. See |vim9-reload| for
more information.

:vim9cmd :'<,'>source
:10,18source ++clear
*:source!*
:so[urce]! {file} Read Vim commands from {file}. These are commands
