> 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!
