;~ This relies on the following:
;~ Unlike a variable, an array element can't contain a string and a pure number simultaneously.
;~ A field's "capacity" is the size of string it can hold before it needs to expand. If it doesn't hold a string it has no capacity.
;~ SetFormat hasn't been used to remove the decimal point from the floating-point string format. (If var is float has the same limitation, since it always converts the value to a string for analysis.)
