请问为什么log中
GLOBAL DEPT sales ？？？
GLOBAL COMPANY ABC
a DATA step that contains a SYMPUT routine within a macro definition suppose
to create local macro variables
谢谢答复 |

发帖数: 202 | 3 谢楼上，我加了一个%put _user_;在外面，结果还是
41 %put _user_;
GLOBAL DEPT sales
GLOBAL COMPANY ABC
而且问题中的%put _user_;是在macro 定义里的可log中就是显示
GLOBAL DEPT sales
GLOBAL COMPANY ABC |

反正
symputX(,,'G')产生global,
symputX(,,'L')产生local. |

You can create a global macro variable with
* a %LET statement (used outside a macro definition)
* a DATA step that contains a SYMPUT routine
* a SELECT statement that contains an INTO clause in PROC SQL
* a %GLOBAL statement.

You can create local macro variables with
* parameters in a macro definition
* a %LET statement within a macro definition
* a DATA step that contains a SYMPUT routine within a macro definition
* a SELECT statement that contains an INTO clause in PROC SQL within a
macro definition
* a %LOCAL statement.

说的是macro定义在data步里面吧？ 不适用于你的这个例子吧？ |

我觉得这就是在data step里定义了一个 symput routine，
我的理解错误？ |
