sys.get_fdfval()

Purpose:

sys.get_fdfval() returns the float value of a display field.

Usage:

fval = sys.get_fdfval(<DFLABEL>);

Arguments:

<DFLABEL> - The label for the field. This is an integer from 0 to num display fields - 1. sys.cur_field may be used.

Returns:

The float value of the display field.

-1.0 - possible error

Where Used:

sys.get_fdfval() can be called from anywhere but will probably be called from a verify pcl for a display field.

Example:

Description:

sys.get_fdfval() returns the float value of a display field. You may want to use this in the verify PCL for a display field if you need to do some type of special formatting. You can use this in a global PCL and not need to know the name of a display field in order to get its value. Just pass sys.cur_field as the <DFLABEL>.

Bugs/Features/Comments:

It is impossible to tell if a -1.0 return means an error or if the value of the field really is -1.0. However, the only errors are DFLABEL out of range, or the data type of the display field is not a float.
