Hello,

can you pls show us that DB2 structure? You posted REAL type, but data are organized with WORD type, also can you post how you get to that MB_DATA_ADDR - 40002 value?

I HAVE CHANGED A LOT OF THING BUT I GET NO VALUE !

I WANT TO READ THE VALUE 18458 OF THE CURRENT BUT NO SOLUTION

THE DB2 sturcture 

i have changed the parametrs of the mb-client but no results yet 

status =0 

now i can read this  data  (ADD 18458).

, i wonder if i can read all this data from what i will start ?

THANK FOR THE HELP 

Nice to hear that is ok. With MB_DATA_LEN parameter you can define LENGTH of filled data in buffer, so experiment with this, simply how much next Words you want have filled , also be carefuly with length of buffer, but you have 101 Words. Give pls info about success.

now i cannot read data i dont know why :(  i try to do the same thing i mean start with the address 18458 , i try to use 418458 (i added 4 ) in the firt test i succeed but now no ,

i changed my mb-unit-id to 17 ( in dicimal) but no result yet 

please help me quick as possible
