 		 #165661 - error
Responding to: ???'s previous message
I have some questions regarding 2 instructions

Save filename.txt
Valid_ID: DB 30h,34h,31h,35h,44h,38h,41h,31h,46h,31h
MOV DPTR,#Valid_ID

 


what will be loaded into DPTR register???

and also what effect will have the next instruction over the content of the Accumulator
Save filename.txt
MOVC A,@A+DPTR
 

i've read the instruction set explanations but i didn't quite catch the meaning of this instruction.
Many thanks!
