-**usage: -set overwrite VALUE**
+**fScan Reference Manual, Chapter 2 (CmdLineOptions): set overwrite**
+===== Set Overwrite -- Set the file overwrite flag =====
+**usage:**\\
+ ** -set overwrite **\\
+ ** -set overwrite 0 **
+The OVERWRITE flag is used to indicate whether fScan will overwrite existing data files.
+By default, OVERWRITE is zero and any attempt to overwrite an existing file will generate an error message.
+If OVERWRITE is non-zero, write operations will overwrite existing data files without generating any message.
+The OVERWRITE flag can be set temporarily using the [[jvs:fscan:manual:chapter2:writeover|-WRITEOVER (-w)]] command. Set this way, the flag remains set only until the next file writing command. This allows you to selectively indicate which data files to overwrite.\\
+For example:
+<code>
+  -o exam.wdf -w           ; force writing of file named "exam.wdf", even if it already exists
+  -o -w                    ; force writing of current data set to file, even if that file exists
+</code>
+The default behavior of the OVERWRITE flag can be changed using the -SET OVERWRITE command.
+<code>
+  -set overwrite          ; allow any file to be overwritten without generating error messages
+  -set overwrite 0        ; default is to not allow existing files to be written unless -w is used
+</code>
