Description:
This attribute holds the minimum length which a character variable must
have in order to be able to store the longest value currently present (at any row) in a
specified column of the supplied Table. This does not include room for a trailing null
character. The required column name should be placed inside the parentheses in the
attribute name. If the named column holds vector values, then the attribute value
is the length of the longest element of the vector value.
Type:
Integer,
read-only.
Applicability

All Tables have this attribute.
Notes:
If the named column holds numerical values, the length returned is the length of the
largest string that would be generated if the column values were accessed as strings.
