HP gnu source-level debugger 5992-4701 Pretty print arrays. This format is more, Default is off

If you have a pointer and you are not sure where it points, try 'set print symbol-filename on'. Then you can determine the name and source file location of the variable where it points, using 'p/a pointer'. This interprets the address in symbolic form. For example, here GDB shows that a variable ptt points at another variable t, defined in 'hi2.c':

((gdb)) set print symbol-filename on

((gdb)) p/a ptt

$4 = 0xe008 <t in hi2.c>

WARNING! For pointers that point to a local variable, 'p/a' does not show the symbol name and filename of the referent, even with the appropriate set print options turned on.

Other settings to control how different kinds of objects are printed:

set print array, set print	Pretty print arrays. This format is more
array on	convenient to read, but uses more space. The
	default is off.
set print array off	Return to compressed format for arrays.
show print array	Show whether compressed or pretty format is
	selected for displaying arrays.
set print elements	Set a limit on how many elements of an array
number-of-elements	GDB will print. If GDB is printing a large array,
	it stops printing after it has printed the number
	of elements set by the set print elements
	command. This limit also applies to the display
	of strings. When GDB starts, this limit is set to
	200. Setting number-of-elementsto zero
	means that the printing is unlimited.
show print elements	Display the number of elements of a large array
	that GDB will print. If the number is 0, then the
	printing is unlimited.
set print null-stop	Cause GDB to stop printing the characters of an
	array when the first NULL is encountered. This
	is useful when large arrays actually contain only
	short strings. The default is off.
set print pretty on	Cause GDB to print structures in an indented
	format with one member per line, like this:
	$1 = {
	next = 0x0,
	flags = {
	sweet = 1,
	sour = 1
