; Get the file permissions for the "hamlet.xml" file on the server.

; Note: Filesystem permissions on Linux/Unix/MacOSX are typically written in octal (POSIX file permissions).  For example 0644 is octal.
; To convert to decimal: octal 644 = 6*8^2 + 4*8 + 4 = 420 (decimal)
; 
; The server may return a permissions value (in octal) such as 100644.
; The "100" indicates the file type, such as regular file or directory. 

; Show the decimal value of the permissions
ConsoleWrite("decimal permissions value: " & $iPermVal & @CRLF)

; To set the file permissions, pass the integer value.
; Let's change the permissions to 0664, which is 6*8^2 + 6*8 + 4 = 436 (decimal)
