I7DB8CNV Utility
I7DB8CNV converts the character data in an IMAGE database from any
Hewlett-Packard 7-bit national substitution set to ROMAN8. The program
is a special version of the DBLOAD.PUB.SYS program, and the conversion is
done as part of a database load. The procedure for running I7DB8CNV is:
1. Enter:
RUN DBUNLOAD.PUB.SYS
This unloads the database to tape.
2. Enter:
RUN DBUTIL.PUB.SYS,ERASE
This erases the database data.
3. Enter:
RUN I7DB8CNV
This converts the data and reloads it into the database.
I7DB8CNV requests the following:
1. The 7-bit national substitution set where the conversion is to be
made.
2. The database name.
3. The utility prompts the user: Convert all data fields of type X
or U?. A YES or Return response converts all data fields of type
U or X. A NO response prompts the user in each data set for each
field of type U or X.
The single field in an automatic data set is not proposed for
conversion. Whether or not its values are converted depends on the
response to the item(s) it is linked to for detail data set(s). At the
end of each data set, the user is asked to confirm that the correct
fields to be converted from that data set have been selected. Again, a
Return is a YES answer; an N allows the user to change the data fields
in the data set to be converted.
I7DB8CNV then loads the database from tape. As each record is read,
those fields that were selected have their data converted according to
the algorithm for the 7-bit national substitution set selected at the
beginning of the program.
I7DB8CNV does not allow 8-bit data (bytes with the high-order bit set) in
the data fields it is trying to convert. The utility does not abort, but
the field in question is not converted, and a warning is issued:
8-bit data encountered in item [itemname in DS data set]
If the program should abort for any reason during the conversion, the
user must log on again to clear the temporary files used during the
conversion process before running the program again.
Figure D-2 shows the dialog from a sample run of the I7DB8CNV program.
