EEPROM READ AND WRITE

STATREAD:

MOV A, #WTCMD ;LOAD WRITE COMMAND
CALL OUTS
MOV A, #00H
CALL OUT
CALL CREAD
MOV A, R1
MOV STATUS, A
RET

why MOV A , #WTCMD, give me the error A45 enerywhere in the code?

Please zip your full code and post it.
Which assembler are you using ?

I'm using keil uvision5.
attached is the rar file of the code.

The full error is
control_unit.asm(1294): error A45: UNDEFINED SYMBOL (PASS-2)
UNDEFINED SYMBOL means the assembler does not know what WTCMD means.

Somewhere there should be a file containing definitions of things like WTCMD.
Where did you get this code ?
