Class Usage

In addition to the value of the 4GL variable, these objects contain member variables, among which is the variable value also containing the numeric value. For this reason, it is legal to write "order_line.itemprice" in your expression as a shortcut for "order_line.itemprice.value".

The member variable fglValue contains a String representing the numeric value as formatted by the DVM, taking into consideration such parameters as USING, DBMONEY, etc. In contrast, the member variable value is a numeric value without formatting.
