Environment Variables
You can use DOS environment variables anywhere in an AutoIt script. As in DOS
batch files, just include the variable enclosed in percent (%) symbols.
For example, if you want to send the current DOS path to the notepad window you
could do:
Run, notepad.exe
WinWaitActive, Untitled - Notepad
Send, This is the DOS path %PATH%
e.g. This example sets the variable test and then outputs it in a
messagebox.
SetEnv, test, This is some output
MsgBox, 0, Example, %test%
N.B. Because of its special status, if you want to actually use a percent
sign without it being changed into a variable, you must use the escape character
'\' first.
e.g.
Send, This will send a single percent sign \%
You can also use "SetEnv" to
set variables..
N.B. Many AutoIt commands specifically state that they take a variable as a
parameter, in these cases the % symbol is NOT used. A number of the
examples that come with AutoIt demonstrate this.
