I am trying to set up a function call to move values within a DB which holds  a struct of UDT Billet Information. Every memory location corresponds to a location 1,2,3, etc. The Function call takes inputs that correlate to a physical location. The UDT is 14 bytes long so position 1 starts at memory location 14 and position 2 will start at 28. So if the from location is 1 and the two location is say 3 I need to move address 14 to address 42. Above is what I have but need to change the SRCBLK and DSTBLK to use the address calculated. Don't quite understand the pointer math as that was written by someone else I am modifying it for a similar use. TEMP3 and TEMP4 are of type DWORD
