If LC_NUMERIC is effectively set to a value that sets non-null thousands separators or that uses comma as the radix character, you need to take extra precautions when working with CSV files that contain numeric strings that represent non-integral values, or integral values greater than 999 or less than -999.
You are right, Don, as always. In his entry posting Aaron stated that his SysAdmin has traced back the problem to the changed LANG-entry in /etc/environment, so i took it that none of the applicable LC_-variables are defined in his case, because these would have overridden the old as well as the new setting.

Still, its a good idea to explain the interdependence of LANG and LC_ALL the other LC_-variables.

I hope this helps.

locale

LOCALE(1)						    BSD General Commands Manual 						 LOCALE(1)

NAME

     locale -- display locale settings

SYNOPSIS

     locale [-a|m]
     locale [-ck] name [...]

DESCRIPTION

     locale displays information about the current locale, or a list of all available locales.

     When locale is run with no arguments, it will display the current source of each locale category.

     When locale is given the name of a category, it acts as if it had been given each keyword in that category.  For each keyword it is given,
     the current value is displayed.

OPTIONS

     -a       Lists all public locales.

     -c name ...
	      Lists the category name before each keyword, unless it is the same category as the previously displayed keyword.

     -k name ...
	      Displays the name of each keyword prior to its value.

     -m       Lists all available public charmaps.  Darwin locales do not support charmaps, so list all CODESETs instead.

OPERANDS

     The following operand is supported:

     name is the name of a keyword or category to display.  A list of all keywords and categories can be shown with the following command:

     locale -ck LC_ALL

ENVIRONMENT

     LANG	  Used as a substitute for any unset LC_* variable.  If LANG is unset, it will act as if set to "C".  If any of LANG or LC_* are
		  set to invalid values, locale acts as if they are all unset.

     LC_ALL	  Will override the setting of all other LC_* variables.

     LC_COLLATE   Sets the locale for the LC_COLLATE category.

     LC_CTYPE	  Sets the locale for the LC_CTYPE category.

     LC_MESSAGES  Sets the locale for the LC_MESSAGES category.

     LC_MONETARY  Sets the locale for the LC_MONETARY category.

     LC_NUMERIC   Sets the locale for the LC_NUMERIC category.

     LC_TIME	  Sets the locale for the LC_TIME category.

SEE ALSO

     localedef(1), localeconv(3), nl_langinfo(3), setlocale(3)

STANDARDS

     The locale utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     locale appeared in Mac OS X 10.4

Darwin								  August 27, 2004							    Darwin
