19.4 Screen Size

Certain commands to No value for GDBN may produce large amounts of information output to the screen. To help you read all of it, No value for GDBN pauses and asks you for input at the end of each page of output. Type <RET> when you want to continue the output, or q to discard the remaining output. Also, the screen width setting determines when to wrap lines of output. Depending on what is being printed, No value for GDBN tries to break the line at a readable place, rather than simply letting it overflow onto the following line.

Normally No value for GDBN knows the size of the screen from the terminal driver software. For example, on Unix No value for GDBN uses the termcap data base together with the value of the TERM environment variable and the stty rows and stty cols settings. If this is not correct, you can override it with the set height and set width commands:

set height lpp

show height

set width cpl

show width

These set commands specify a screen height of lpp lines and a screen width of cpl characters. The associated show commands display the current settings.

If you specify a height of zero lines, No value for GDBN does not pause during output no matter how long the output is. This is useful if output is to a file or to an editor buffer.

Likewise, you can specify ‘set width 0’ to prevent No value for GDBN from wrapping its output.

set pagination on

set pagination off

Turn the output pagination on or off; the default is on. Turning pagination off is the alternative to set height 0.

show pagination

Show the current pagination mode.
