As far as I know, the only officially supported way to do this is via the writeUserBlock and readUserBlock functions.

yes, you can read and write to userblock using writeUserBlock and readUserBlock functions, You can find the sample programs under this folder  
C:\DCRABBIT\_10.64\Samples\UserBlock
