关于AS400中的一个%函数用法

Question

判断一个表
名字 TABLE
记录格式 TABLER

如果用%函数   %STATUS   是不是等于 01218

这个用IF 怎么写  我一直尝试   IF       %STATUS(XXX) = 01218

XXX 我用了 表名 记录格式名 等等 都报错  有
*RNF0396 20 A      051800   組み込み関数 %STATUS のパラメーター XXXXXXX が正しくな   
                            い。 %STATUS は無視されます。                           
XXXXX我用的是一个封装对表所有操作的程序名

有谁用过 这个%函数 麻烦告诉下用法  非常感谢

ILE RPG Reference
-----------------------------------
%STATUS (Return File or Program Status)

%STATUS{(file_name)}      -----如果file_name不写,应该是最近一次操作的文件
%STATUS returns the most recent value set for the program or file status.
%STATUS is set whenever the program status or any file status changes, usually
when an error occurs.
If %STATUS is used without the optional file_name parameter, then it returns the
program or file status most recently changed. If a file is specified, the value
contained in the INFDS *STATUS field for the specified file is returned. The INFDS
does not have to be specified for the file.
%STATUS starts with a return value of 00000 and is reset to 00000 before any
operation with an ’E’ extender specified begins.
%STATUS is best checked immediately after an operation with the ’E’ extender or
an error indicator specified, or at the beginning of an INFSR or the *PSSR
subroutine.

*..1....+....2....+....3....+....4....+....5....+....6....+....7...+....
* The ’E’ extender indicates that if an error occurs, the error
* is to be handled as though an error indicator were coded.
* The success of the operation can then be checked using the
* %ERROR built-in function. The status associated with the error
* can be checked using the %STATUS built-in function.
