Database Connectors reads the decimal point character from the environment variable DECIMAL_POINT. If DECIMAL_POINT is set, Database Connectors uses that character. If the variable is not set, Database Connectors uses the decimal character that is encoded in the XFD file.
The two most common decimal indicators are the period “.” and the comma “,” characters. The comma is used often in European code and is often indicated in COBOL programs by the DECIMAL POINT IS COMMA clause.
