DAT2PCD.EXE
By Jim Landers
DAT2PCD.EXE was written to convert previous versions of PostCard data
files with a ".DAT" extension to the new .PCD data format required by
PostCard Version 7.0 and above. If you are using PostCard for the first
time and are now using version 7.0 or above, you don't need DAT2PCD.EXE.
The new field sizes are as follows:
New .PCD Field Size Old .DAT Field Size
Name: 32 characters 30 characters
Address: 32 characters 30 characters
City: 26 characters 15 characters
State: 20 characters 2 characters
Zip: 10 characters 5 characters
Phone #1: 18 characters 14 characters
Phone #2: 18 characters 14 characters
Note: 40 characters 40 characters
FileName: 12 characters <New with Version 7.0>
To use DAT2PCD.EXE, run the program. When it asks you for a data file
to convert, simply type in the name of the file with your old .DAT
extension. The program expects the source file to be in the current direc-
tory and will write the target file to the current directory also.
DAT2PCD.EXE works on one file at a time and does not support wildcards;
however, files only need to be converted one time. After you have
converted your data files to the new ".PCD" format, you will no longer need
DAT2PCD.EXE.
The new field sizes better accommodate address labels, since the names
of practically all cities found in a medium-sized atlas can now be fitted
on the city line without abbreviation. The telephone number fields are
better for systems that require a suffix such as "9" to get an outside line
or a "," to pause for dial tone. They also make international telephone
numbers more readable. In addition, the Zip code field can now accommodate
ten-position zip codes. The author recognizes the new field sizes still
won't cover 100% of all possibilities, but size, capacity and speed are
still design criteria for PostCard, and the new field sizes are compro-
mises. PostCard now serves more users needs, but it still does not try to
be all things to all people.
Before you attempt to convert data files, the author suggests you fol-
low an orderly procedure to avoid problems:
1. Make a new temporary subdirectory on your hard drive and copy all
of your data files with a ".DAT" extension to it, leaving your
current ".DAT" files unchanged.
2. Use DAT2PCD.EXE to convert each file to a new file with a ".PCD"
extension. After you have finished, erase the old files with a
".DAT" extension.
3. Unzip PostCard version 8.3 into your temporary subdirectory and
run POSTCD83.EXE to make necessary changes to POST.PRM to reflect
your system's needs: Pulse or Tone dialing, Default Data File, etc.
using <Ctrl-O>. Try the new version out thoroughly while you're in
the temporary subdirectory. If everything is working properly, then
transfer your new program and ".PCD" files to your working sub-
directory.
Although version 8.3 has new features, it is substantially the same
as previous versions, but it won't be able to use your old ".DAT" files
until they have been converted. The ".PCD" extension was chosen, by the
way, because the ".DAT" extension is used by many different programs
today, and ".PCD" helps differentiate PostCard data files from other types
of data files.
