danlo

I want input a number (e.g 123) by using 4x4 keypad, and then, store it into EEPROM and display it to LCD..

'VAR

---

number···· VAR···· word

'Data

---

store_num ·DATA··· 120

Main:
........··········· ' code to get number, number = 123
write 120, number
.......

What wrong of my programe?·Would you·give me an example? ...thank you so much!!

What you are doing in the Main: is storing the value of 'number' in EEPROM location 120. Is that what you want?

The examples in the Help file cover the use of this instruction quite well.

If you have more questions, posting the working part of your program would help everyone understand your problem a bit better.

Cheers,

store_num DATA 120

If you're trying to store at address 120 you should write it like this

store_num DATA @120,0

the @ defines the address, the 0 is a dummy data

otherwise store_num's address is determined by the compiler.

if you don't use @ the label "store_num" represent the address, so you might as well use it:

write store_num,number
