Determine the environment variable's value however you like, for example using

Code: Select all

Call DSExecute("UNIX", "echo $HASHPATH", HashDirPath, Code)

The result is in the variable called HashDirPath.

Build your SETFILE command.

Code: Select all

Command = "SETFILE " : HashDirPath : "/" : HashedFileName : " " : HashedFileName : " OVERWRITING"

Execute your command

Code: Select all

Call DSExecute("UV", Command, Output, Code)

Check that the value of Code is zero, which indicates success.

But...

You don't need SETFILE if you're only reading via the Routine.

Determine the environment variable's value however you like, for example using

Code: Select all

Call DSExecute("UNIX", "echo $HASHPATH", HashDirPath, Code)

The result is in the variable called HashDirPath.

Build the pathname of the hashed file.

Code: Select all

HashFilePath = HashDirPath : "/" : HashedFileName

Open the hashed file using OpenPath.

Code: Select all

OpenPath HashFilePath To filevariable
On Error
   * code to handle fatal error on Open
End
Then
   * code executed if opened OK
   * (including Read statements probably)
   * finishing with
   Close filevariable
End
Else
   * code executed if failed to open
End

echo IS a DOS command. However, you will need "DOS" rather than "UNIX" in the DSExecute call.

What is the exact error message returned from DSExecute? (The error message is in the third argument, the exit status is in the fourth argument.)
