Hey guys. I'm just learning the basis of embedded with Keil. I'm working on the 8051. Doing this program to find the factorial of a number. Got the code online and I can't understand why it won't run. Help me out, guys.
1.ORG 0000H 2.MOV R0, #05H 3.MOV A, R0 4.ACALL FACT 5.FACT: DEC R0 6. CJNE R0, #1, REL 7. SJMP STOP 8.REL: MOV B,R0 9. MUL AB 10. ACALL FACT 11.STOP: END 12.END
I added the last END after it showed a warning about missing END statement. I get the following errors/warnings: Q3.s(0): error A21: EXPRESSION WITH FORWARD REFERENCE NOT PERMITTED Q3.s(11) SYNTAX ERROR Target not created.
