Certain commands to @value{GDBN} may produce large amounts of
information output to the screen. To help you read all of it,
@value{GDBN} pauses and asks you for input at the end of each page of
-output. Type @key{RET} when you want to continue the output, or @kbd{q}
-to discard the remaining output. Also, the screen width setting
-determines when to wrap lines of output. Depending on what is being
-printed, @value{GDBN} tries to break the line at a readable place,
-rather than simply letting it overflow onto the following line.
