Question

单片机编译时出现错误

出现UNKNOW CONTROL OR BAD ARGUMENT”怎么办
另外，汇编语言，编译工具是A51,开始就出现，不是后面的语法问题！

Answer 1

A51中$可以调用一些指定的控制指令，例如文件的调用$include (c8051f040.inc)
$NOMOD51；使A51汇编器预定义的SFR无效等
当$后面跟的指令错误或无效时。就会出现这种错误提示。

下面是所有的$调用的控制指令

ELSEIF General Assemble block if condition is true and a previous IF or ELSEIF is false.
ENDIF General Ends an IF block.
ERRORPRINT Primary Specifies the file name for error messages.
GEN General Includes all macro expansions in the listing file.

INCLUDE2 General Includes the contents of another file.
LIST General Includes the assembly source text in the listing file.
MACRO Primary Enables preprocessor expansion of standard macros.
MOD_CONT Primary Enables 24-bit contiguous addressing for Dallas Semiconductor devices.

NOCASE Primary Disables case-sensitive symbol names. All symbols are converted to uppercase.
NOCOND Primary Excludes (from the listing file) conditional source lines skipped by the preprocessor.
NODEBUG Primary Excludes debugging information from the object file.
NOERRORPRINT Primary Disables error messages output to the screen.
NOGEN General Excludes macro expansions from the listing file.
NOLINES Primary Excludes line number information from the generated object module.
NOLIST General Excludes the assembly source text from the listing file.
NOMACRO Primary Disables preprocessor expansion of standard and MPL macros.
NOMOD51 Primary Suppresses SFRs definitions for classic 8051 devices
NOMPL Primary Disables preprocessor expansion of MPL macros.
NOOBJECT Primary Disables object file generation.
NOPRINT Primary Disables listing file generation.
NOREGISTERBANK Primary Disables memory space reservation for register banks.
NOSYMBOLS Primary Excludes the symbol table from the listing file.
NOSYMLIST General Excludes subsequently defined symbols from the symbol table.
NOXREF Primary Excludes the cross-reference table from the listing file.
OBJECT Primary Specifies the name for the object file.
PAGELENGTH Primary Specifies the number of lines on a page in the listing file.
PAGEWIDTH Primary Specifies the number of characters on a line in the listing file.
PRINT Primary Specifies the name for the listing file.
REGISTERBANK Primary Reserves memory space for register banks.
REGUSE General Specifies registers modified by the specified function.
RESET General Sets symbols, which may be tested by IF or ELSEIF, to false.
RESTORE1 General Restores settings for the LIST and GEN directives.
SAVE1 General Saves settings for the LIST and GEN directives.
SET General Sets symbols, which may be tested by IF or ELSEIF, to true or a specified value.
SYMBOLS Primary Includes the symbol table in the listing file.
SYMLIST General Includes subsequently defined symbols in the symbol table.
TITLE Primary Specifies the page header title in the listing file.
XREF Primary Includes the cross-reference table in the listing file.

Answer 2

这句话的意思是：
“未知的控制或者错误的参数（自变量）”

必须看程序清单上下文，才能知道“怎么办”。
看程序清单上下文之前，先得知道您用的是什么语言，哪个版本的编译，用的是哪种单片机，等等，等等。

【关于补充】
开始出现，有几种可能：
(1)是否文件头上有include，而包含的文件不合适？
(2)是否开发界面上操作有误（我对A51及有关的开发工具不熟悉，其它系统中有些操作是有条件的）？

有些系统中，编译和链接是分步进行的，你的这个提示是什么时候出现的？
