******************************** WARNING! ********************************

The format for the data files in CT-Label 3.0 has changed. You must use the
program CTCONVRT.EXE to convert data files from prior versions of CT-Label to
the new format. This program will work on all versions of CT-Label data files
prior to version 3.0.

In addition to a change in the data format, data files created by CT-Label 2.1
and earlier contain a problem which could prevent recovery, if that need arises.
The flag portion of each data record which is used to indicate a deleted record
was not properly initialized with versions of CT-Label prior to 3.0. This
normally does not present a problem unless it is necessary to recover a file
using the new rebuild routine of CT-Label 3.0. To correct the problem, the
program file CTCONVRT.EXE is included with version 3.0 of CT-Label. The syntax
for CTCONVRT is simply

CTCONVRT filename

where 'filename' is the name portion of the data and index files that are used
by CT-Label. It is only necessary to run CTCONVRT one time with each set of
files. If it is not used, however, and your data file becomes corrupt, it may
not be possible to use the new rebuild routine to recover at least a portion
of the corrupt file.

Another side effect of this problem is that the new browse utility may not
function correctly when identifying a record that is not properly initialized.
Use the program CTCONVRT as described above to fix this problem.
