What change streets does

Change streets makes a list of all the desired changes and stores it in memory.

It then checks that each of the changes is valid, and throws out the invalid ones.  (writing the error to the log file).

The next step is to create each of the streets which don't yet exist in the database, but which are placed in the "Good Street" column.

Then, each accident record is checked to see if it refers to one of the bad streets.  If it does, it is changed to refer to the new good street.

Finally, all of the bad streets are removed from the database so that they don't appear in the street names dialog.

Note: Users of earlier versions of IMW may have used the change streets script.  This is no longer available.  The new change streets can change as many streets in one pass as the script took for each desired change.  The Pd' Programming BBS contains a free utility for converting your script(s) to the new change streets file format.
