Although
isblank() can be used to check for blank values, and the
blank command to make them blank, it is better to consider blank and zero as equals. If you need support for "does not have a value", in Visual FoxPro you can use null values.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
