playerslight Posts: 1064 Rating: (72)	I can do the pointer as i had it working last night for 1 block move What i was trying to do is loop through the 20 calls . all data is in 1 data block instead of calling the blockmove 20 time i wanted to loop it . so what i need to do is use a temp variable for the datablock and a temp variable for the pointer so i can make function called by a loop for the 150 different data blocks and 20 udts in each function .i did have working using load and transfer but with 20 elements for 5 element but for 20 the function is just to big and had to follow and prone to mistakes
