COP CPS Instruction

[travis 0]

Hi all, Does anyone know what is the value should I put for the "length" operand? Example, I have a UDT which contains 8 real and 1 string20. Should I just put 1 ? I read from the reference manual. It said that " You must test and confirm that the instruction doesn’t change data that you don’t want it to change. The COP and CPS instructions operate on contiguous memory. They do a straight byte-to-byte memory copy. In some cases, they write past the array into other members of the tag. This happens if the length is too big and the tag is a userdefined data type. " Could someone guide me, please. Thanks in advanced.

If you are copying TO your UDT then the length is in units of 1 UDT. The length is in terms of the destination type. From the outside a UDT appears as a single unit (which a great part of the power).
