Fore more information on NDBs, NSBs, DBDs, PSBs and UDFs, see the Natural for DL/I documentation.

This section describes menu functions and selection list options provided to perform a SYSMAIN function on DL/I subfiles and the syntax that applies when using direct commands.

Fields in the DL/I Subfiles Menu

The DL/I Subfiles menu contains all SYSMAIN functions required for the processing of DL/I subfiles. The fields provided in the menu are described in the following table:

Field Explanation
Code
Specifies the function to be performed as described in Description of Functions:
   
C Copy subfile.
D Delete subfile.
L List subfile.
M Move subfile.
Sel. List
Specifies whether selective processing or automated processing is used:
   
Y Yes.
Selective processing is activated. A selection list is displayed when processing DL/I subfiles. This is the default setting. For the columns, fields and line commands available on a selection list, see Selection Lists for DL/I Subfiles.
N No.
Selective processing is deactivated.
Name The name of the DL/I subfile to be processed or a range of names: see also Specifying a Range of Names.
Type
The type of DL/I subfile to be processed. You must specify either of the following types:
   
D Only NDBs and UDFs are processed. This is the default setting.
P Only NSBs are processed.
Database The database ID (DBID) of a source or a target database.

The source database contains the FDIC system file where the DL/I subfile to be processed is stored. The target database contains the FDIC system file to which the DL/I subfile is to be copied or moved.

Valid database IDs are 1 to 65535.

File The file number (FNR) of a source or a target FDIC system file.

Valid file numbers are 1 to 65535.

The source file contains the DL/I subfile to be processed. The target file is the file to which the DL/I subfile is to be copied or moved.

Name
(next to File)

Only applies to VSAM files.

The DDNAME/FCT entry for the source or target file number.
Replace
Specifies whether a DL/I subfile is to be replaced when using the move or copy function:
   
Y Yes.
A DL/I subfile with the same name which exists in the target environment is replaced.
N No.
A DL/I subfile with the same name which exists in the target environment is not replaced. This is the default setting.

Direct Command Syntax for DL/I Subfiles

This section shows the syntax that applies when performing a SYSMAIN function on a DL/I subfile by using direct commands in either online or batch mode. For general instructions on using direct commands, refer to Executing Commands.

For explanations of the keywords and variable values used in the syntax diagrams below, refer to Keywords and Variables in Direct Commands. The symbols in the syntax diagrams correspond to the syntax symbols used for system commands. These symbols are explained in System Command Syntax in the System Commands documentation.

The syntax of the where-clause and the with-clause are identical for each command.

This section covers the following topics:

COPY and MOVE

Examples:

COPY DL1 SUBFILE1 TYPE D FM DBID 1 FNR 5 TO DBID 2 FNR 5
C DL1 SUBFILE REP FM FNR 6 TO FNR 7 TYPE D
COPY DL1 SUBFILE1 TYPE P TO DBID 3 FNR 7 
MOVE DL1 SUBFILE1 TYPE D FM DBID 1 FNR 5 TO DBID 2 FNR 5
M DL1 SUBFILE1 REP FM FNR 6 TO FNR 7 TYPE D

DELETE and LIST
