Will be in this way: Original: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Expected: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Thx all!

Hello, One possible method would be using indirect addressing plus loops.Data stored MW100 reversed as you like to MW102,It is also possible to do it in a function: LAR1 P#M 100.0 LAR2 P#M 103.7 L 16 lp: T #zahlen A [AR1,P#0.0] = [AR2,P#0.0] +AR1 P#0.1 L -1 +AR2 end: NOP 0 L #zahlen LOOP lp Also check snapshot of what I have tested.

Result as in attached file LAR1 P#M 10.0 LAR2 P#M 128.0 L 16 lp: T #zahlen L MW [AR1,P#0.0] T MW [AR2,P#0.0] +AR1 P#2.0 L -16 +AR2 L #zahlen LOOP lp

Dear Maselo, Thank you for your feedback and great work to change it to do it for 32 bit. @ manmeet, please note the initiator of thread asked clearly to " invert a bit sequence from a MW " in a single WORD(16-Bit). Thank you for your solution for inverting sequence of 16 successive memory addresses but it is off topic and may mislead people referring to this thread in future. Thank you for understanding! Many regards from Hamid Hosseini

Please inform the moderator to remove my earlier post. STL instructions are members of a step7, In creation of one program and only one program. Manmeet
