Batch/TSO TBDRIVER (DK1TDRV) Command Descriptions

TBDRIVER (DK1TDRV) is the tableBASE driver command processor for Batch/TSO. DK1TDRV can be invoked in a batch job (see JCL for DK1TDRV), or interactively through the TSO CLIST TBDR, or the tablesONLINE/ISPF menu. The TBDRIVER (DK1TDRV) program accepts tableBASE-like commands from a terminal or a file and invokes tableBASE to execute them. TBDRIVER also has additional commands (referred to as macros) created to make long tasks easier such as PRINT TABLE (PR).

XT

 XT,tablename,wpswd

Eliminate all generations of a table from library
12 This is a special TBDRIVER (DK1TDRV) command.
13 Same as 14 but list of tables to be matched is all tables in the current library search list (LIB-LIST).
14 An asterisk (*) may be used as a wildcard character in the table name. An asterisk can only be used on its own or at the end of a string. A standalone asterisk denotes all table names. An asterisk at the end of a string denotes zero or more characters. Any characters after the first asterisk will be ignored. For example:

OR,* opens all tables
OR,B* opens all tables beginning with the letter B
OR,*S* opens all tables; characters after the first asterisk are ignored
OR,F*T* opens all tables beginning with the letter F.

The input command is processed against all the tables matching the table name mask. For example, when the close table (CL) command is issued to table HOWARD* the command closes all the tables and alternates with HOWARD in the first six characters of the name. While wildcard commands are in progress, libraries in the library search list (LIB-LIST) should not be updated, otherwise results returned will be unpredict­able.

15

The GD command display of the DDNAME field is increased from eight bytes to 12 bytes. This allows display of VTS:xxxxxxxx for tables accessed by a linked VTS-TSR. This may affect applications which post-process the output from TBDRIVER steps.

16 TABLENAMEMASK is a wild-card form as above, or contains no asterisks, for example, CAT in which case it is assumed to be equivalent to CAT*. The list matched is all tables in the current library search (LIB-LIST).
