Symptoms:
	PHCO_27242:
	( SR:8606168690 CR:JAGad37968 )
	The more(1) and page(1) do not support files
	greater than 2GB.

	( SR:8606232376 CR:JAGae01611 )
	In a multibyte locale environment, more(1) hangs when an
	invalid character is entered and erased by backspace,
	while entering command from stdin.

	( SR:8606174802 CR:JAGad44048 )
	more(1) command dumps core or gives "read error"
	when viewing the binary files.

	( SR:8606233175 CR:JAGae02398 ) Duplicate
	( SR:8606227499 CR:JAGad96557 )
	In a multibyte locale environment, more(1) gives wrong
	output when input is from stdin.

	( SR:8606223261 CR:JAGad92364 )
	more(1) does not work as expected with input file containing
	large number of escape characters (^A).

	PHCO_26083:
	( SR:8606232376 CR:JAGae01611 )
	more(1)  hanges when an invalid character entered
	and deleted  under multibyte locale while entering
	command from stdin.

	( SR:8606233175 CR:JAGae02398 )
	more(1) works incorrectly for input from stdin in multibyte
	locale.

	( SR:8606227499 CR:JAGad96557 )
	more(1) command is giving invalid output under multi-byte
	locale environment.

Defect Description:
	PHCO_27242:
	( SR:8606168690 CR:JAGad37968 )
	The more(1) and page(1) commands exits with
	error message "Value too large to be stored
	in data type" when used on large files(>2GB).

	For example:
	$ ll test_file
	-rw-rw-rw-   1 root  sys  2560000000 [...snipped..]
	$more test_file
	[..Snipped..]Value too large to be stored in data type

	Resolution:
	more(1) is a 32 bit binary and the data types used
	initially couldn't handle values greater than 2GB.
	Hence when the size of the file exceeds 2GB, more(1)
	used to report the above mentioned error message and
	exit.

	Now, more(1) is enhanced to support large files.
	The variables are replaced with new variables
	capable of holding large values.

	( SR:8606232376 CR:JAGae01611 )
	more(1) hangs when an invalid character(e.g. ^K) is
	entered and deleted by pressing backspace under multibyte
	locale environment at !command prompt.

	For example:
	$export LANG=ja_JP.SJIS
	$ll -R /dev | more
	[....snipped....]
	crw-rw-rw-   1 root       other   [...snipped....]
	!abc^K       <== This is entered from keyboard

	Now if ^K is deleted by pressing backspace, it hangs.

	Resolution:
	more(1) checks for the number of column position of the
	characters to be deleted. When a character is an invalid
	character(^K) more(1) is not able to recognize it under
	multibyte environment. The code is changed to recognize
	it properly.

	( SR:8606174802 CR:JAGad44048 )
	more(1) command core dumps or gives "read error"
	when viewing the binary files. For example:
	$ more <data file>
	[....snipped.....]
	memory fault(core dump)

	Resolution:
	more(1) reads blocks of data. A variable is used
	to count the number of control characters read
	in each block. This variable was not initialized
	prior to each block being read, as a consequence
	more(1) tries to write additional blocks which
	eventually results in a core dump.

	Now more(1) code has been changed to properly
	initialize the variable before reading each block.

	Though more(1), dumping core while viewing binary
	files is resolved, there are few problems still
	exist when reading binary files. As more(1) uses
	the terminal interfaces, some of the control
	characters in the binary data file could be
	interpreted by the terminals. We advise users to
	use the more(1) utility to view text files and
	use other commands such as xd(1) for viewing
	binary data files.

	( SR:8606233175 CR:JAGae02398 ) Duplicate
	( SR:8606227499 CR:JAGad96557 )
	For some multibyte locales, more(1) is eating up some
	characters from the output when the input is from stdin.

	For example:
	$export LANG=ja_JP.eucJP
	$wc file
	66 93 3269 file
	$more file | wc
	66 93 3269
	$more < file | wc
	62 90 3142
	^^ ^^ ^^^^
	(The above output is wrong)

	Resolution:
	more(1) was checking wrongly for the EOF while reading a
	file. In a multibyte environment, it was not able to
	process the input properly when a multibyte character
	spans across the boundary of two successive input
	buffers. The code is changed to take care of this
	situation. If an incomplete character is encountered at
	the boundary of input buffer, it is carried forward to
	next buffer.

	( SR:8606223261 CR:JAGad92364 )
	more(1) behaves incorrectly when the input file contains
	large number of escape characters (^A).

	For example:
	1. it hangs after reading certain number of escape
	   characters (^A) from the input file.

	2. The terminal session gets killed with pipe error
	   message when more(1) takes input from stdin and the
	   output is piped to wc(1) command.
	   $more < file | wc
	   Pipe error
	   Connection closed.

	Resolution:
	There was special handling for escape character (^A) at
	the time of input processing by more(1). The code has been
	modified to take care that this handling is delayed till
	the output processing.

	PHCO_26083:
	( SR:8606232376 CR:JAGae01611 )
	More was not dealing properly with multibyte nonprintable
	character.It used to hang when a nonprintable character
	was edited and erased at !command mode under multibyte
	locales.

	Resolution:
	The code was modified to handle multibyte non-printable
	characters properly.

	( SR:8606233175 CR:JAGae02398 )
	More garbles output when fed multibyte characters
	through a pipe.It was eating up some bytes when contents
	of a file, created under a multibyte locale, is fed to more
	through a pipe.

	Resolution:
	The code of more(1) is changed to take care of multibyte
	characters fed through a pipe.

	( SR:8606227499 CR:JAGad96557 )
	more(1) was eating up some character when fed through
	pipe under multibyte locale environment.

	Steps to reproduce the problem.

	$ export LANG=ja_JP.eucJP
	$ man 2 pause > file
	$ wc file
	66 93 3269 file
	$ more file | wc
	66 93 3269
	$ cat file | more | wc
	62 90 3142

	Resolution:
	The code was changed to handle multibyte characters.
