Filecopy using a Windows environmental variable

[Willow]

I have a Windows XP environmental varible called datadir which has the value of c:\daily

With Autoit, I attempting to copy a file from the folder c:\daily by using filecopy as below.

;Allow the use of environmental variables

Opt("ExpandEnvStrings", 1)

FileCopy("@datadir\dat0509.txt", "c:\backup", 8)

The problem is, the file is not being copied...probably due to the wrong syntax however I cannot figure out how to accomplish this seemingly easy task...

Any help would be much appreciated.

Thanks

Willow

Have a look at EnvGet

Use 2 percent signs i.e %variable% to expand the environmental variable.

Opt("ExpandEnvStrings", 1)
FileCopy("%datadir%\dat0509.txt", "c:\backup", 8)
