Displays the script lines most recently executed.

ListLines , OnOff



If blank or omitted, the history of lines most recently executed is shown. [v1.0.48.01+]: An optional first parameter was added, which can be either On or Off. It affects only the behavior of the current thread as follows:

On: Includes subsequently-executed lines in the history. This is the starting default for all scripts.

Off: Omits subsequently-executed lines from the history.

[v1.1.30+]: The decimal values 1 and 0 may be used in place of On and Off, respectively.


ListLines (with no parameter) is equivalent to selecting the "View->Lines most recently executed" menu item in the main window. It can help debug a script.

ListLines Off/On can be used to selectively omit some lines from the history, which can help prevent the history from filling up too quickly (such as in a loop with many fast iterations). ListLines Off may also improve performance by a few percent.

Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).

[v1.1.28+]: The built-in variable A_ListLines contains 1 if ListLines is enabled and 0 otherwise.

On a related note, the built-in variables A_LineNumber and A_LineFile contain the currently executing line number and the file name to which it belongs.
