/ FUNCTION NAME: changestats()
/
/ FUNCTION: examine/change statistics for a player
/
/ AUTHOR: E. A. Estes, 12/4/85
/
/ ARGUMENTS:
/	bool ingameflag - set if called while playing game (Wizard only)
/
/ RETURN VALUE: none
/
/ MODULES CALLED: freerecord(), writerecord(), descrstatus(), truncstring(), 
/	time(), more(), wmove(), wclear(), strcmp(), printw(), strcpy(), 
/	infloat(), waddstr(), cleanup(), findname(), userlist(), mvprintw(), 
/	localtime(), getanswer(), descrtype(), getstring()
/
/ GLOBAL INPUTS: LINES, *Login, Other, Wizard, Player, *stdscr, Databuf[], 
/	Fileloc
/
/ GLOBAL OUTPUTS: Echo
/
/ DESCRIPTION:
/	Prompt for player name to examine/change.
/	If the name is NULL, print a list of all players.
/	If we are called from within the game, check for the
/	desired name being the same as the current player's name.
/	Only the 'Wizard' may alter players.
/	Items are changed only if a non-zero value is specified.
/	To change an item to 0, use 0.1; it will be truncated later.
/
/	Players may alter their names and passwords, if the following
/	are true:
/	    - current login matches the character's logins
/	    - the password is known
/	    - the player is not in the middle of the game (ingameflag == FALSE)
/
/	The last condition is imposed for two reasons:
/	    - the game could possibly get a bit hectic if a player were
/	      continually changing his/her name
/	    - another player structure would be necessary to check for names
/	      already in use
