Purpose: The USE SF command, without the LOG option, sets up a specified System File (SF) use in place of terminal input, as if the lines in the file were typed at the terminal. The USE SF LOG command designates a LOG file to record a copy of terminal input and output.
USE SF name
USE NO SF
USE SF name /AS/ LOG [ONLY] [APPEND]
USE NO SF LOG
|
USE SF name |
declares a SF to be used as the terminal input source. If the file name extension is .CMD, it need not be specified. Any other extension must be specified. |
|
USE NO SF |
terminates input from the currently declared SF and all nested SF’s. |
|
USE SF name /AS/ LOG |
specifies that all terminal input and output (except edit characters) is to be written on the designated SF. |
|
ONLY |
suppresses terminal display while terminal output is written on the LOG file. If ONLY is not specified, terminal output is both written on the LOG file and displayed at the terminal. |
|
APPEND |
specifies that any text previously contained in the LOG file is to be retained. The new text written into the file will be attached to the end of the old text. |
|
USE NO SF LOG |
terminates output to the currently declared LOG file. A SF that is functioning as a LOG file cannot be read until it is first closed with the USE NO SF LOG command. |

00020 USE DS BOOKS_DBM2
00030 EXTRACT
