TYPES dtype {TYPE RANGE OF type}|{LIKE RANGE OF dobj} 
            [INITIAL SIZE n].


Derives a table type for a ranges table. A ranges table is a standard table with a standard key and a specially structured row type whose internal definition can be displayed as follows in ABAP syntax:

TYPES: BEGIN OF linetype,
         sign   TYPE c LENGTH 1,
         option TYPE c LENGTH 2,
         low    {TYPE type}|{LIKE dobj},
         high   {TYPE type}|{LIKE dobj},
       END OF linetype.

The additions TYPE and LIKE determine the data type of the components low and high:

  • type can be a non-generic data type from ABAP Dictionary, a non-generic public data type of a public data type or global class, a non-generic data type local to a program, or any ABAP type from the tables of predefined ABAP types. The generic ABAP types c, n, p, and x are implicitly extended to the standard length without decimal places from the tables of predefined ABAP types.
  • dobj can be a data object visible at this point, whose type is used for both components. Generically typed formal parameters cannot be specified for dobj within a procedure.

The addition INITIAL SIZE is synonymous with the definition of normal internal table types.
