Error Messages

Schema Processor Error Messages

The Schema Processor accesses three ﬁles:

• The text ﬁle (DBSTEXT) containing the schema records and Schema Processor

commands for processing.

• The list ﬁle (DBSLIST) containing the schema listing, if requested, and error messages,

if any.

• The root ﬁle, if requested, created as a result of an error-free schema.

Any ﬁle error which occurs while accessing any of these ﬁles causes the Schema Processor

to terminate execution. A message indicating the nature of the error is sent to $STDLIST

(and to the list ﬁle, if the list ﬁle is different from $STDLIST).

Schema Processor command errors can occur. They neither cause termination nor do they

prohibit the creation of a root ﬁle. In some cases, however, the resultant root ﬁle will differ

from what might have occurred had the commands been error free. Command errors are

added to an error count which, if it exceeds a limit (see chapter 3), will cause the Schema

Processor to terminate execution.

Note that if the LIST option is active (see chapter 3), error messages for command errors

and syntax errors appear in the list ﬁle following the offending statement. If the NOLIST

option is active, only the offending statement, followed by the error message, is listed.
