This is a PPWIZARD command line switch.
This switch should rarely be required as html mode is the default mode unless all input files end in the extension ".X" (its use is recommended for rexx source code).
On non unix operating systems lines end with carriage return followed by linefeed, with the internet unix has finally won (it only requires lines to terminate with a linefeed). Web servers and browsers do not require the carriage return (which they ignore). You can save an extra one character per line with use of the /CRLF switch.
This switch can be used any number of times and will affect all input masks that follow. It also becomes the default mode for all files produced via the #Output command. If an input mask comes first then any preconfigured extension information (see /ExtnInfo) will be used or if not available PPWIZARD will abort.
