: val = page_screen_output ()
: old_val = page_screen_output (new_val)
: page_screen_output (new_val, "local")

Query or set the internal variable that controls whether output intended for the terminal window that is longer than one page is sent through a pager.

This allows you to view one screenful at a time. Some pagers (such as less—see ‘Installation’) are also capable of moving backward on the output.

When called from inside a function with the "local" option, the variable is changed locally for the function and any subroutines it calls. The original variable value is restored when exiting the function.

See also: more, page_output_immediately, PAGER, PAGER_FLAGS.
