Executes IMAGE/SQL utility commands from a command file instead of the standard input
device.
Prerequisites |
 |
None, but for successful execution of the command file,
you must meet prerequisites of all commands in the command file.
Description |
|
Use the XEQ command to execute IMAGE/SQL utility commands from a file instead of the
standard input device.
For example, if an ATCLOG file has been saved as a permanent file, it can be
used to reissue the commands
stored in the log file.
When an XEQ command is entered, the IMAGE/SQL utility reads the specified file and
executes
the commands until it reaches the end-of-file.
When the end-of-file is reached, control returns to the original command input
device (in session mode, the terminal, or in batch mode, the batch input
device).
Note that unless the command file contains an EXIT or QUIT command, you
remain in the IMAGE/SQL utility when the XEQ command terminates.
During the execution of command files, what you see at the terminal depends
on the setting of the ECHO command.
When ECHO is on, the IMAGE/SQL utility displays lines at the terminal as
they are read from the command files. Both comments
and commands in the file are displayed. Regardless of the setting of the
ECHO command, normal command output and error messages are displayed
at the terminal.
In batch mode, if an error occurs
during the execution of an XEQ file,
the IMAGE/SQL utility closes the XEQ file and terminates the job.
Example |
|
In the following example, the contents of the file DOATTACH are listed
using the
MPE/iX PRINT command. The XEQ command then executes the
commands stored in
the DOATTACH file. Because commands are not displayed as they are executed,
it can be assumed that
the ECHO command option is off.
>>:PRINT DOATTACH
SET TURBODB ORDER4 ⇐ contents of XEQ file
SET SQLDBE PARTSDBE ⇐ " "
ATTACH ⇐ " "
QUIT ⇐ " "
>>
>>XEQ DOATTACH XEQ command issued
