Edsim51始终无效标签错误

Question

我在MacOS上使用EDSIM51。但我总是得到标签无效 - ****是关键字错误。阅读文档（用户指南和示例页面），但仍然不知道我在哪里犯错误。我从Edsim的网站上下载了示例代码，但它的官方示例也出现了相同的错误。

例如， 这是一个LCD示例，摘自他们的网站：

; put data in RAM
    MOV 30H, #'A'
    MOV 31H, #'B'
    MOV 32H, #'C'
    MOV 33H, #0 ; end of data marker


; initialise the display
; see instruction set for details


    CLR P1.3        ; clear RS - indicates that instructions are being sent to the module

; function set  
    CLR P1.7        ; |
    CLR P1.6        ; |

    CLR P1.4        ; | high nibble set

    SETB P1.2       ; |
    CLR P1.2        ; | negative edge on E

    CALL delay      ; wait for BF to clear  
                    ; function set sent for first time - tells module to go into 4-bit mode
; Why is function set high nibble sent twice? See 4-bit operation on pages 39 and 42 of HD44780.pdf.

    SETB P1.2       ; |
    CLR P1.2        ; | negative edge on E

    SETB P1.2       ; |

                ; function set low nibble sent

    SETB P1.3       ; clear RS - indicates that data is being sent to module
    MOV R1, #30H    ; data to be sent to LCD is stored in 8051 RAM, starting at location 30H

    CALL delay          ; wait for BF to clear

delay:

    DJNZ R0, $

**和错误：**标签无效 - FİNİSH是关键字

你能告诉我我错过了什么吗？
