1. Using QuickFix commands			*quickfix* *Quickfix* *E42*

Vim has a special mode to speedup the edit-compile-edit cycle.  This is
inspired by the quickfix option of the Manx's Aztec C compiler on the Amiga.
The idea is to save the error messages from the compiler in a file and use Vim
to jump to the errors one by one.  You can examine each problem and fix it,
without having to remember all the error messages.

In Vim the quickfix commands are used more generally to find a list of
positions in files.  For example, |:vimgrep| finds pattern matches.  You can
use the positions in a script with the |getqflist()| function.  Thus you can
do a lot more than the edit/compile/fix cycle!

If you have the error messages in a file you can start Vim with: >
	vim -q filename

From inside Vim an easy way to run a command and handle the output is with the
|:make| command (see below).

The 'errorformat' option should be set to match the error messages from your
compiler (see |errorformat| below).

					*quickfix-stack* *quickfix-ID*
Each quickfix list has a unique identifier called the quickfix ID and this
number will not change within a Vim session. The |getqflist()| function can be
used to get the identifier assigned to a list. There is also a quickfix list
number which may change whenever more than 'chistory' lists are added to a
quickfix stack.

						*location-list* *E776*
A location list is a window-local quickfix list. You get one after commands
like `:lvimgrep`, `:lgrep`, `:lhelpgrep`, `:lmake`, etc., which create a
location list instead of a quickfix list as the corresponding `:vimgrep`,
`:grep`, `:helpgrep`, `:make` do.
						*location-list-file-window*
A location list is associated with a window and each window can have a
separate location list.  A location list can be associated with only one
window.  The location list is independent of the quickfix list.

When a window with a location list is split, the new window gets a copy of the
location list.  When there are no longer any references to a location list,
the location list is destroyed.

						*quickfix-changedtick*
Every quickfix and location list has a read-only changedtick variable that
tracks the total number of changes made to the list.  Every time the quickfix
list is modified, this count is incremented. This can be used to perform an
action only when the list has changed.  The |getqflist()| and |getloclist()|
functions can be used to query the current value of changedtick.  You cannot
change the changedtick variable.

The following quickfix commands can be used.  The location list commands are
similar to the quickfix commands, replacing the 'c' prefix in the quickfix
command with 'l'.

							*E924*
If the current window was closed by an |autocommand| while processing a
location list command, it will be aborted.

							*E925* *E926*
If the current quickfix or location list was changed by an |autocommand| while
processing a quickfix or location list command, it will be aborted.

							*:cc*
:cc[!] [nr]		Display error [nr].  If [nr] is omitted, the same
:[nr]cc[!]		error is displayed again.  Without [!] this doesn't
			work when jumping to another buffer, the current buffer
			has been changed, there is the only window for the
			buffer and both 'hidden' and 'autowrite' are off.
			When jumping to another buffer with [!] any changes to
			the current buffer are lost, unless 'hidden' is set or
			there is another window for this buffer.
			The 'switchbuf' settings are respected when jumping
			to a buffer.
			When used in the quickfix window the line number can
			be used, including "." for the current line and "$"
			for the last line.

							*:ll*
:ll[!] [nr]		Same as ":cc", except the
