If factor 1 is specified, factor 2 is subtracted from factor 1 and the difference is placed in the result field. If factor 1 is not specified, the contents of factor 2 are subtracted from the contents of the result field.
Factor 1 and factor 2 must be numeric, and each can contain one of: an array, array element, field, figurative constant, literal, named constant, subfield, or table name.
The result field must be numeric, and can contain one of: an array, array element, subfield, or table name.
