SDDBC's Files
SDDBC uses the formal file designators SDIN as the input file and SDLOG
as the log file. File equates are allowed for both files.
The Input File
SDDBC accepts input from the file SDIN. The default for SDIN is $STDINX.
Redirecting SDIN to a file, whether in session or batch mode, causes
SDDBC to accept input from the specified file. The specified file must
be an unnumbered file or SDDBC will not execute correctly. Redirection
is achieved by using the following MPE file equation:
:FILE SDIN = command file
The next time SDDBC is executed, the input will be accepted from the
file, command file.
The Log File
When SDDBC is executed, all valid commands, with the exception of the
REDO command, are logged to the file SDLOG. A valid command is a command
without parse errors. If [[CONTROL]] Y is entered in the middle of a
command, then the entire command is not logged. SDLOG gives the user the
foundation for running SDDBC with previously inputted commands.
When SDLOG is redirected to a file other than itself, all input entered
for that session will be saved in the specified file. If the file does
not exist, then SDDBC will build it as a fixed length temporary ASCII
file with record size 80 bytes. If the file already exists, then SDDBC
will ask for permission to overwrite it. To redirect SDLOG to a file,
use the following MPE commands:
:FILE SDLOG = command file
:RUN SDDBC.PUB.SYS
If SDLOG has not been redirected to a file, then SDLOG is session
temporary. An MPE SAVE command may be used to save SDLOG as a permanent
file. An example of this is:
:RUN SDDBC.PUB.SYS
:SAVE SDLOG
:RENAME SDLOG, LOGFILE
The file LOGFILE, now contains the previously entered input. User
responses are not logged.
