Sample Run (DOS / JDK 1.2)

Note: If your browser supports color, some text on this page should appear in red. This was added to the HTML code after the fact to highlight certain information and was not produced by the program.

Also: All superscripts were added for footnote references and were not produced by the program.

Screen Output

This program writes a list of the current system properties
to a text file in the current directory.

Please enter a name for the text file: ABCD
  65  66  67  68  13  10 <-- ASCII codes input
  Length of input BEFORE removing line separator = 6
  Length of input AFTER  removing line separator = 4
  65  66  67  68 <-- ASCII codes retained

System properties written to ABCD

Notice that the keyboard buffer initially contained the ASCII codes for "ABCD" (65-68) plus the codes 13 and 10 (the values of the carriage return and line feed characters, which comprise the DOS line separator).

Footnotes:

1. This is the time zone setting on my PC.
2. Codes for the DOS line separator (CR/LF).
3. This is interesting. Internally, Windows 95 reports that it's really Windows "4.0".
4. The DOS file separator (backslash).
