Hi,

Can any one tell me the difference between fully-specified data types and generic data types.

HI

Generic table types

INDEX TABLE

For creating a generic table type with index access.

ANY TABLE

For creating a fully-generic table type.

Data types defined using generic types can currently only be used for field symbols and for interface parameters in procedures . The generic type INDEX TABLEincludes standard tables and sorted tables. These are the two table types for which index access is allowed. You cannot pass hashed tables to field symbols or interface parameters defined in this way. The generic type ANY TABLE can represent any table. You can pass tables of all three types to field symbols and interface parameters defined in this way. However, these field symbols and parameters will then only allow operations that are possible for all tables, that is, index operations are not allowed.

Fully-Specified Table Types

STANDARD TABLE or TABLE

For creating standard tables.

SORTED TABLE

For creating sorted tables.

HASHED TABLE

For creating hashed tables.

Fully-specified table types determine how the system will access the entries in the table in key operations. It uses a linear search for standard tables, a binary search for sorted tables, and a search using a hash algorithm for hashed tables.

Fully specified data types can be also known as complete data types for which the length need not be specified. example for such data types are i,d,t.

whereas the data types p,x,c are incomplete for which the length needs to be specified.

Generic data types can be used if the data type of a variable is determined at the run time.

Some generic data types are : any, numeric, simple, ctype, csequence etc
