You can include most standard X toolkit command-line options when you issue the prism command; for example, you can use the -geometry option to change the size of the main Prism window. See your X documentation for information on these options. Also, note these limitations:
The -font, -title, and -rv options have no effect.
The -bg option is overridden in part by the setting of the Prism.textBgColor resource, which specifies the background color for text in Prism; see " Changing Colors".
X toolkit options are ignored if you use -C to run Prism in commands-only mode.
