Hi,
Jabaco has no built-in LSET command to byte-copy one UDT into another UDT.
Jabaco usually copies variables just by assigning them (without SET).
There is a Cast() function to map otherwise incompatible types, but this does not work for your example as Java simply refuses to do what you want.

You might go on and dig this forum. Stefan Schnell invented a VarPtr library to do all sorts of fancy things with addresses of variables.
Use "Option Explicit" as first line of your code to uncover unresolved references.

Copying UDTs byte by byte is rather implementation dependent. You have to know exactly how the UDT variables are represented in memory.
This is quite against the philosophy of Java were all variables and objects are "somewhere" in memory without known size and without known location.

Success!
