Attributes 'Length __TOC__ Description 'Length is an array type attribute. It may be used with or without an input parameter. Without an input parameter, 'Length is an integer that represents the length of the first dimension of the array type. With an input parameter, 'Length(N) is an integer that represents the length of the Nth dimension of the array type. N must be a positive number within the dimensions of the array. Example If you declare: type My_Vector is array (1 .. 7) of Integer; type My_Matrix is array (1 .. 5, 1 .. 10) of Integer; then Assert (My_Vector'Length = 7); Assert (My_Matrix'Length(1) = 5); Assert (My_Matrix'Length(2) = 10); Assert (My_Vector'Length(1) = My_Vector'Length); Assert (My_Matrix'Length(1) = My_Matrix'Length); See also Wikibook Ada Programming Ada Reference Manual 13 3 Operational and Representation Attributes K Language-Defined Attributes Length Length
