Field4.assignBytes missing on Compact Framework

I've just bought CodeBase 6.5 and have been using it with .NET.  One of
my data tables requires binary data to be stored, I have defined the
field type as r4charBin.  I am using Field4.assignBytes() to store the
binary data.

However when I've ****ted the code to the Compact Framework I have found
that the implementation of Field4.assignBytes() is missing.

How do you work with binary fields in the Compact Framework ?
