    Formula definition

    You can set Code39 in a worksheet using the following formula:

    =BC_CODE39(value, color, backgroundColor, showLabel, labelPosition, labelWithStartAndStopCharacter, checkDigit, nwRatio, fullASCII, fontFamily, fontStyle, fontWeight, fontTextDecoration, fontTextAlign, fontSize, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom)
