- DATAMAGE dBass files conversion utility
-
-
-
- Conversion of a dBase file to the DATAMAGE format (standard, headerless random-
- access files) should be accomplished in two steps. The CONVERTER.EXE program
- will do the "raw" conversion, and make a new datafile in the DBSEFILE sub-
- directory off \MAGE.
-
-
- STEP 1:
-
-
- The \MAGE\DBSEFILE dir was made by the automatic HD installation batch file.
- Perhaps you have removed it since then. It MUST BE present to accept the
- converted file as the CONVERTER program offers no choice of where to place it's
- output. Nor does it support the re-organization of the file.
-
- Before you start CONVERTR, be certain that there is no datafile currently in
- the DBSEFILE dir. If a file is present it will be over-written and DESTROYED
- by the next dBase file to be converted. Convertr will not inform you of it's
- presence, nor will it offer you a chance to abort.
-
- After starting convertr you simply enter the pathname for the dBase file to be
- converted and an increment value for numbering the new records in the DATAMAGE
- file, and the file is converted.
-
- After the conversoin is complete start SCRNBASE and check the first, last and
- some intermediate records in the new file. Your "raw" file will not be
- indexed, and will contain exactly what the dBase file does with one exception:
- at the time of this writing the character and note fields will be truncated at
- the 35th character.
-
- Future modifications to CONVERTR will include the option to expand these
- fields. A char/note field of 105 bytes would produce three DATAMAGE fields of
- 35 bytes each, and the data would be moved in. This version of CONVERTR will
- be distributed with the registered versions as soon as it's done. (My
- customers don't think I should be spending time on DATAMAGE programs, they
- think I should be writing THEIRS! and it DOES pay better....)
-
-
- STEP 2:
-
-
- After your file has been checked you may wish to modify it in order to take
- advantage of more DATAMAGE features (indexing) and to expand the (cheezy) 10
- character field names allowed by dBase. The only bad thing about re-naming the
- fields is that POWER COPY will be un-able to automatically identify the fields.
- Of course you can enter the data, you'll only do this once (per file).
-
- The new file is re-organized like any other DATAMAGE file. Start the DBSEMAKR
- program and edit the format to your liking. Then start POWER COPY and move the
- data into the new format. This creates a permanent "home" for the new file,
- and frees the DBSEFILE dir for the next dBase file, if any.
-
- Before converting the next dBase file you should empty the DBSEFILE directory
- by entering DEL C:\MAGE\DBSEFILE\*.*. Also note that the sahreware version
- will fail to access files comprising over 300 records. Unless you have a
- registered version there's not much point in converting files larger than 300
- reacords, as you can't access them.
