12.9 @group: Prevent Page Breaks

The @group command is used to hold an example together on one page. Use it inside an @example or similar construct to begin an unsplittable vertical group, which will appear entirely on one page in the printed output. Terminate the group by a line containing only @end group. This command has an effect in TeX output only.

The @group and @end group commands need to be inside the @example and @end example commands, thus:

@end group
@end example

Although @group would make sense conceptually in a wide variety of contexts, its current implementation works only within @example and variants, and within @display, @format, @flushleft and @flushright. See Quotations and Examples. (What all these commands have in common is that each line of input produces a line of output.)
