如何使用 CATX 函数连接 space？

Question

我需要将数字和字符串连接成一行，但用 space 分隔。

我尝试了 5 种方法，但没有得到想要的结果。

%LET lim1 = 113;
%LET lim2 = 166;

测试 1：

%LET linha = %SYSFUNC(CATS(De,&lim1,a,&lim2,clientes));
%PUT &linha;

输出 1:

De113a166clientes

测试 2：

%LET linha = %SYSFUNC(CATS('De ',&lim1,' a ',&lim2,' clientes'));
%PUT &linha;

输出 2（错误）：

30         %LET linha = %SYSFUNC(CATS('De ',&lim1,' a ',&lim2,' clientes'));
NOTE: Line generated by the macro function "SYSFUNC".
30          'De '113' a '166' clientes'
            _____   _____
            49      49
NOTE 49-169: The meaning of an identifier after a quoted string might change in a future SAS release.  Inserting white space 
             between a quoted string and the succeeding identifier is recommended.

测试 3：

%LET linha = %SYSFUNC(CATX(' ','De ',&lim1,' a ',&lim2,' clientes'));
%PUT &linha;

输出 3（错误）：

29         %LET linha = %SYSFUNC(CATX(' ','De ',&lim1,' a ',&lim2,' clientes'));
NOTE: Line generated by the macro function "SYSFUNC".
29          'De '' '113' '' a '' '166' '' clientes'
            ________   ___________
            49         49
NOTE 49-169: The meaning of an identifier after a quoted string might change in a future SAS release.  Inserting white space 
             between a quoted string and the succeeding identifier is recommended.

测试 4：

%LET linha = %SYSFUNC(CATX(' ',De,&lim1,a,&lim2,clientes));
%PUT &linha;

输出 4（错误）：

NOTE: Line generated by the macro function "SYSFUNC".
29          De' '113' 'a' '166' 'clientes
              ___   ___ ___   ___
              49    49  49    49
NOTE 49-169: The meaning of an identifier after a quoted string might change in a future SAS release.  Inserting white space 
             between a quoted string and the succeeding identifier is recommended.

测试 5：

%LET linha = %SYSFUNC(CATX(*,De,&lim1,a,&lim2,clientes));
%PUT &linha;

输出 5:

De*113*a*166*clientes

测试 5 非常接近我的需要，但我需要将 * 替换为空白 space。

我需要： De 113 a 166 clientes

很遗憾，我没有成功。

Answer 1

在宏中，您不需要使用 CAT 来组装源代码文本。

只需在所需上下文中解析宏变量即可。

%LET lim1 = 113;
%LET lim2 = 166;
%LET linha = De &lim1 a &lim2 clientes;
%PUT &=linha;
----- LOG -----
LINHA=De 113 a 166 clientes

如果在带引号的字符串或字符串值计算的 DATA 步上下文中使用宏变量值，则解析应在字符串文字的双引号内（除非宏值已经按字面意思用双引号引起来文字)

data have;
  input (part1-part3) ($);
datalines;
De a clientes
Si o consumer
Mr A Sky
;
%LET lim1 = 113;
%LET lim2 = 166;

data want;
  set have;
  result = catx(' ', part1, "&lim1", part2, "&lim2", part3);
  put result=;
run;
----- LOG -----
result=De 113 a 166 clientes
result=Si 113 o 166 consumer
result=Mr 113 A 166 Sky
