PB f_evaluate DW Atributes

powerbuilder f_evaluate yang memeriksa atribut pada suatu datawindow apakah berisi nilai atau bentuk ekspresi

f_evaluate_attribute
A function used to get the attribute value as the datawindow interprets it; either the result of the expression or the value if there is not an expression.

Example:
string ls_value
ls_value = f_evaluate_attribute(dw_1, dw_1.getrow(), 'col1', 'Protect')

If protect has an EXPRESSION in it, the expression will be evaluated and the result returned.
If it does NOT have an EXPRESSION, then it will return whatever was entered on it.
