Using Document Tools

This section outlines the main differences in document tools used in SunOS release 4 and the Solaris 7 operating environment.

• The Solaris 7 operating environment provides a set of PostScript filters and device-independent fonts. However, most SunOS release 4 TranScript filters have SunOS release 5.7 equivalents while a few less common ones do not. In SunOS release 5.7 systems, there is no T_EX filter, no pscat (C/A/T) filter, and no raster image filter.

• The Solaris 7 operating environment provides device-independent troff, with the following features: SunOS release 4 troff input files work with Solaris 7 troff; troff default output goes to the standard output instead of the printer. Therefore, you must specify a printer when you send troff output to the printer.
