- | -wA anatoutfile\\ | + | The WRITEOVER command temporarily sets the internal OVERWRITE flag. |
- | -wE endfile\\ | + | By default, OVERWRITE is zero and any attempt to overwrite an existing file will generate an error message. |
- | -wW waitfile | + | If OVERWRITE is non-zero, write operations will overwrite existing data files without generating any message. |
- | ===== ===== | + | When OVERWRITE is set using the WRITEOVER command, the flag remains set only until the next file writing command. This allows you to selectively indicate which data files to overwrite.\\ |
+ | For example: | ||
+ | < | ||
+ | | ||
+ | -o -w ; force writing of current data set to file, even if that file exists | ||
+ | </ | ||
+ | The default behavior of the OVERWRITE flag can changed using the [[jvs: | ||
+ | < | ||
+ | -set overwrite | ||
+ | -set overwrite 0 ; default is to not allow existing files to be written unless -w is used | ||
+ | </ | ||
