The GLS locales contain end-user formats, which you do not usually need to change. You can set the DBMONEY environment variable, however, to customize the appearance of the currency notation. For information on the DBMONEY environment variable, see the IBM Informix: Guide to SQL Reference.
A monetary end-user format string specifies a format for the manipulation of internal DECIMAL, FLOAT, and MONEY values as monetary literal strings. IBM Informix products use the following precedence to determine the end-user format for a MONEY value:
CLIENT_LOCALE identifies the client locale; if it is not set, the client locale is the default locale.
If DBMONEY is not set, and no locale is specified, the currency symbol is the dollar sign, the thousands separator is the comma, and the decimal separator is the period.
