Thanks everyone for the responce, here is what I'm trying to do...kindly guide me.

Data @0, 5 ,"29690" 'initially saved to memory

-to check if the code is the same with the data stored in the eeprom, Lookdown() is used for security password.
What i'm trying todo is to change "29690" with this code..
************************************************** *******
' Saving to EEPROM
@ READKEYPAD _myvar
if scroll = 3 then
Serout PortC.1, 6, [$FE,1]
Serout PortC.1, 6, [$FE,$C0]
for countera = 0 to 4
@ READKEYPAD _Key
Serout PortC.1, 6, [$FE,($C0+5),"["]
Serout PortC.1, 6, [$FE,($C0+6+COUNTERA),"*"]
Serout PortC.1, 6, [$FE,($C0+7+COUNTERA),"]"]
code[countera]=key
Write countera+1, code[countera] ; write the digit to EEPROM
next countera
Serout PortC.1, 6, [$FE,1,"Saving..."]
pause 1000
WRITE 0,5
Endif
**************************************
'To check if the new number is saved I used this code...
@ READKEYPAD _Key
if key = 11 then
read 0,code
serout PortC.1, 6, [$FE, 1,#code]
pause 1000
for countera = 0 to 4
read countera+1,code
serout PortC.1, 6, [$FE, $82+countera,#code]
pause 1000
next countera
Endif

it shows that i succeeded overwriting the "29690" using the above code, But when I try to use it for password entry using the Lookdown(), I get Access denied.
Originally the code is from Darrel and Steve.


Thanks,
Joe
