Processing Lines 

The most powerful method of processing lines involves getting the name of a batch file on the beginning of the line. This allows the words to be passed as arguments to the batch file.

Creating Line Fragments Lines without the usual carriage-return on the end ("line fragments") can have your data lines appended to them to create batch files. Capturing DOS Prompts Since the prompt always appears at the beginning of a line, capturing an intact line -- with a custom prompt you define -- can be used to turn a line of data into a batch file.

Error Messages and Prompts Several DOS commands will place your data on the same line with some kind of message. If the message precedes your data, you can turn the line into a batch file. In addition to the widely-known DATE, six other commands are analyzed.

FOR Unlike the other methods, it doesn't turn your line of data into a batch file. But FOR does the actual job of separating the words in the line. If the words on the line happen to be file masks, FOR is the best choice.

Isolating a Line Sometimes the problem is that you have lots of lines and only want one.
