Generic Files and the
Server Query Processor
Generic Files and the
Current Output Listing File
The generic files QUERY-WORK-AREA, QUERY-SORT-AREA, QUERY-
QPSTATISTICS, and QUERY-QPSTATUS-MESSAGES can be held open for the
lifetime of a server query processor if the Command Interpreter ASSIGN command
(see A Server Query Processor earlier in this section) is specified at the time the server
query processor is created.
By using the generic file names with a server query processor, you can specify where
the server query processor: builds the temporary files, performs sorts, sends statistics,
and sends error messages. Since the QUERY-QPSTATISTICS and QUERY-
QPSTATUS-MESSAGES files are held open for the lifetime of the associated server
query processor, collection of statistics and errors for multiple requests is possible.
The Command Interpreter ASSIGN commands specified when the server query
processor is started cannot be overridden by either ENFORM ?ASSIGN commands nor
Command Interpreter ASSIGN commands specified when the ENFORM process is
initiated. (The server query processor must be stopped and restarted to alter these file
assignments.)
If you assign generic files by specifying either the ENFORM ?ASSIGN command
(during ENFORM processing) or the Command Interpreter ASSIGN command (before
ENFORM is initiated) the server query processor directs output to these generic files
until you clear the ASSIGN command. Generic files that were not assigned when the
server query processor was created are re-opened for each FIND or LIST statement.
If the Generic files QUERY-REPORT-LISTING and QUERY-COMPILER-LISTING are
assigned, these files become the current output listing files under the following
conditions:
QUERY-COMPILER-LISTING file is the current output listing file whenever
ENFORM statements and commands are processed.
QUERY-REPORT-LISTING file is the current output listing file whenever a report
(the output from the LIST statement) is produced unless the ?OUT command
specifies an ?OUT file.
Assignment of any of the other generic files does not affect the current output listing
file.
Table 2-2, shows the forms of ENFORM output (that is, reports, statement and
command output, statistics, and error messages) and the corresponding output file
when generic files are assigned. The default output file is described earlier in this
section.
