Usage

Schema and Subschema Tasks Performed by DELETE IS ON

In the subschema compiler, DELETE IS ON performs the following tasks:

• Deletes version 1 of the subschema load module from the load area of the dictionary when you issue a DELETE SUBSCHEMA command.

  Note: If the subschema load module has a version number other than 1, the load module must be explicitly deleted using the DELETE LOAD MODULE command. For more information about this command, see Chapter 15, “Subschema Statements".

• Erases the PROG-051 dictionary record occurrence associated with the subschema load module, provided the program was built by the subschema compiler and does not participate in any other entity relationships.

In the schema compiler, DELETE IS ON performs the same tasks described above for each subschema associated with the schema named in the DELETE SCHEMA command.

Order of Precedence Applied to the LIST and ECHO Options

The LIST and ECHO options have similar functions; the compiler uses the following order of precedence in determining which options will take effect:

1. NO ECHO
2. NO LIST
3. ECHO
4. LIST

This precedence is interpreted as follows: If NO ECHO is set, the setting of LIST or NO LIST is immaterial; if ECHO and NO LIST both are set, NO LIST takes precedence; and so on.

AUTHORITY FOR ALL Required

Only users whose dictionary description specifies AUTHORITY FOR ALL can specify REGISTRATION OVERRIDE or change the following SET OPTIONS settings:

• SIGNON OVERRIDE
• DISPLAY ALL LIMIT
• INTERRUPT COUNT

Other options can be changed by any user holding the necessary authority to use the compiler.

Overriding SET OPTIONS Defaults on Individual Statements

The SET OPTIONS defaults established for user identification, the destination and format of displayed and punched text, and version assignment can be overridden in individual component statements. Other compiler processing options cannot be so overridden and remain in effect until they are reset, either explicitly (by a subsequent SET OPTIONS statement) or automatically.

Options Reset at the Start of Each Session

All options are reset at the beginning of each session:

• In batch mode, each time the compiler is executed.
• Online, with the first DDL statement issued upon returning to the compiler after either a normal session termination (SIGNOFF) or an abnormal termination of the DC/UCF system. A SIGNON statement that follows session initiation and precedes a SIGNOFF statement (or, in batch mode, the end of the input file) does not begin a new session and, therefore, does not reset all options.

Some Options Reset by the SIGNON Statement

The compiler automatically resets some options to their defaults each time a SIGNON statement is issued. The following table shows which options are reset by the SIGNON statement, which can be changed by the IDD DDDL SET OPTIONS FOR DICTIONARY statement, and the defaults established at installation:

DISPLAY/PUNCH Options Valid for Each Compiler

Not all options available for the DISPLAY WITH/ALSO WITH/WITHOUT clause affect all DISPLAY or PUNCH statements. The options that can be specified in this clause apply to DISPLAY or PUNCH statements for specific components, as shown in the following table:

Default DISPLAY/PUNCH WITH/WITHOUT DETAILS

The default for WITH/WITHOUT DETAILS on the DISPLAY/PUNCH OPTIONS statement is specified at the session level in the SET OPTIONS statement.
