Hello everybody

May you tell me the meaning of"D"and"W"in following S7 instructions?Whitch memory areas are refered by them?
L W [AR1,P#0.0]
T D [AR1,P#6.0]

Best regards,Ali
 
D means load/transfer double word (32 bits)
W means load/transfer word (16 bits)

The contents of AR1 specify the memory area.
