(Pro version only) ANSI (American National Standards Institute) codes are included in various streams of information (most commonly BBS connections), to provide a remote computer with control over cursor positioning, text attributes, etc. They are also used in connections between minicomputers and mainframe computers and the terminals connected to them. The need to use an ANSI filter can be recognized when something like the following example shows up in a file viewed in a text editor: <[0;1;4mas<[m - MC88000 assembler In this example the "as" near the beginning is displayed in a different color than the rest of the line when the ANSI codes are properly processed. The Escape (ASCII 27) codes above have been replaced by the < symbol to make this line printable. The Remove ANSI Escape Sequences filter can be used to filter out these codes and "clean up" the text so that it can be used in standard fashions such as copying and pasting into a word processor. On Unix machines the man (manual) help utility will only allow page-by-page browsing through a file in a forward direction. By piping the man output to a text file, transferring it to a DOS machine, and running it through the Remove ANSI Escape Sequences filter (and the Convert EOL filter - Unix to DOS if desired), a standard DOS editor can be used for browsing through the file, quoting from it, etc. This filter can be enabled on the command line by using the /DA option.
