set_OMRValue
The set_OMRValue method sets the character values within the OMR field to indicate whether a check box is selected.
Description
Each character is assigned the value 0 (ASCII 48; not selected) or 1 (ASCII 49; selected) and the resulting binary string is expressed as a decimal. The following XML example represents a row of six check boxes and the binary string is 001000, which equals 8 in decimal. So, the required value is 8.<F id="1a">
