Starting Apps Most users use the GUI and

either

Double click a desktop icon

Select a list item from the Program menu

You can also issue commands through the command line interface


Starting Apps When you run a application in

Windows, you are specifying an executable file name

For instance, clicking the IE icon tells Windows to “run” iexplore.exe in C:\Program Files\Internet Explorer\ C:\Program Files\Internet Explorer\

iexplore.exe is a fully qualified name


Starting Apps If the fully qualified name is not

specified, Windows searches the Environment Variable called PATH for locations to look for it

Let’s prove it. Start the command prompt

Start button, All Programs, Accessories, Command Prompt


Running a pgm In command prompt we specify

iexplore.exe “Not recognized” message

Now specify fully qualified file name (in quotes) IE started


Running a pgm▮ Now we will set the path value

path = "C:\Program Files\Internet Explorer\"

In command prompt we specify iexplore.exe IE started
