output 1 page at a time

When I run 'select' statements the output does not fit on screen. How can I have my statement display 1 page at a time. Like the UNIX 'more' command.

TIA,

for example your want to display 100 lines at a time, type the following SQL*Plua command on sql prompt

SQL>SET PAGESIZE 100
SQL>SET PAUSE ON

the above code will wait until you press enter for every page.

if you output does not fit into a screen so you can also only set the page size as much as you want (range between 0-50000) then you can scroll up and down.
