我又验证了下,不是因为我刚刚说的那个原因,呵呵……
下面是错误的解释
error . . . . . . . . . . . . . . . . . . . . . . . . Return code 111
__________ not found;
no variables defined;
The variable does not exist. You may have mistyped the
variable's name.
variables out of order;
You specified a varlist containing varname1-varname2, yet
varname1 occurs after varname2. Reverse the order of the
variables if you did not make some other typographical error.
Remember, varname1-varname2 is taken by Stata to mean varname1,
varname2, and all the variables in dataset order in between.
Type describe to see the order of the variables in your dataset.
__________ not found in using data;
You specified a varlist with merge, yet the variables on which
you wish to merge are not found in the using dataset, so the
merge is not possible.
__________ ambiguous abbreviation;
You typed an ambiguous abbreviation for a variable in your data.
The abbreviation could refer to more than one variable. Use a
nonambiguous abbreviation or, if you intend all the variables
implied by the ambiguous abbreviation, append a `*' to the end
of the abbreviation.

我觉得x在这里应当是字符串中的一个字符,所以这样直接定义为x会不会有误呀?期待您的指点!
