batch file - Conditional PAUSE (not in command line)

Question

I like to have a final PAUSE in my *.bat scripts so I can just double click on them in Windows explorer and have the chance to read the output. However, the final PAUSE is an annoyance when I run the same script from the command line.

Is there any way to detect whether we are running the script from a command prompt (or not) and insert the PAUSE (or not) accordingly?

(Target environment is Windows XP and greater.)

Update

I've managed to compose this from Anders's answer:

(((echo.%cmdcmdline%)|find /I "%~0")>nul)
if %errorlevel% equ 0 (
    set GUI=1
) else (
    set CLI=1
)

Then, I can do stuff like this:

if defined GUI pause

Answer 1

@echo off
echo.Hello World
(((echo.%cmdcmdline%)|find /I "%~0")>nul)&&pause

...NT+ only, no %cmdcmdline% in Win9x probably.

As pointed out by E M in the comments, putting all of this on one line opens you up to some edge cases where %cmdcmdline% will escape out of the parenthesis. The workaround is to use two lines:

@echo off
echo.Hello World

echo.%cmdcmdline% | find /I "%~0" >nul
if not errorlevel 1 pause
