Returns the defined length of the current field. |

Size ("Myfield", , "FRM") |
field size or zero |
This example will look for MyField on the form, FRM. It may occur on any section. If the field is located, its size will be returned, otherwise the result is zero (0). Generally, you can assume that a zero result means the field is not defined, since it is unlikely that a field of zero length would be legitimate. |
