HISTSIZE is a shell variable, so this command is needed (you were close):
The message from Kshell is odd. What version are you running? (run the command echo ${.sh.version} to find out. It should give you something like Version JM 93u 2011-02-08 and if it doesn't (or gives you an error) you have a pretty old version of Kshell installed.
In recent versions of Kshell, fc is an alias for hist which is a built-in command. The Kshell doc doesn't mention support for +n, however it is working for me in all of the versions I have installed, the oldest is from 2009.
My gut feeling on this is that your Kshell is old and the in built command doesn't support +n.

LEARN ABOUT PHP
php_uname
PHP_UNAME(3) 1 PHP_UNAME(3)php_uname - Returns information about the operating system PHP is running onSYNOPSIS
string php_uname ([string $mode = "a"])
DESCRIPTION php_uname(3) returns a description of the operating system PHP is running on. This is the same string you see at the very top of the
phpinfo(3) output. For the name of just the operating system, consider using the PHP_OS constant, but keep in mind this constant will con-
tain the operating system PHP was built on.
On some older UNIX platforms, it may not be able to determine the current OS information in which case it will revert to displaying the OS
PHP was built on. This will only happen if your uname() library call either doesn't exist or doesn't work.
PARAMETERS
o $mode
-$mode is a single character that defines what information is returned:
o 'a': This is the default. Contains all modes in the sequence "s n r v m".
o 's': Operating system name. eg. FreeBSD.
o 'n': Host name. eg. localhost.example.com.
o 'r': Release name. eg. 5.1.2-RELEASE.
o 'v': Version information. Varies a lot between operating systems.
o 'm': Machine type. eg. i386.
RETURN VALUES
Returns the description, as a string.
EXAMPLES
Example #1
Some php_uname(3) examples
<?php
echo php_uname();
echo PHP_OS;
/* Some possible outputs:
Linux localhost 2.4.21-0.13mdk #1 Fri Mar 14 15:08:06 EST 2003 i686
Linux
FreeBSD localhost 3.2-RELEASE #15: Mon Dec 17 08:46:02 GMT 2001
FreeBSD
Windows NT XN1 5.1 build 2600
WINNT
*/
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
echo 'This is a server using Windows!';
} else {
echo 'This is a server not using Windows!';
}
?>
There are also some related Predefined PHP constants that may come in handy, for example:
Example #2
A few OS related constant examples
<?php
// *nix
echo DIRECTORY_SEPARATOR; // /
echo PHP_SHLIB_SUFFIX; // so
echo PATH_SEPARATOR; // :
// Win*
echo DIRECTORY_SEPARATOR; //
echo PHP_SHLIB_SUFFIX; // dll
echo PATH_SEPARATOR; // ;
?>
