This is a PPWIZARD command line switch.
PPWIZARD can output some extremely long lines when debug is on (/Debug used etc). This switch allows you to set the longest line allowed. A line if truncated will actually be a bit longer as the fact that a line is truncated if too long is appended to the end of the line.
If "0" is passed then there is no limit on the line length otherwise it must be a positive value.
