reuse么？这两者的区别是什么？

macro is built on the top of procedure;so if procedures cannot do it, macro
won't do it either.
Macro is to help you simplify tasks/minize keystrokes.

发帖数: 3154 | 6 So what is the advantage of macros? Whatever macros can do, a procedure can
be written to do the same, correct? If the answer to this question is "YES",
then what is the point of having macros? I have difficulty explaining this
question to my LD who is learning SAS.
Baozi is sent, BTW.

发帖数: 601 | 11 20 伪币firm. 我问问题有人回答的，一律30伪币。
my answer is: "macro facility" generates sas language or build-in procs/data
step. there are several 'units' in the macro facility, like input stack,
scanner, tokenizer, catalogues, that understand only 'sas macro language'.
Anything other than macro is treated as 'text'in the facility. the output of
the facility is 'sas language'.

发帖数: 148 | 12 Of course you can do everything in SAS without using macro. It is just a
matter of efficiency. For instance, you wan to write a SAS code:
proc print data=whywemustusethegoddamnmacor.itisjustatest;
run;
If you want to print this data set many times, then every time you must
input so long a data name. However,if you use a macro like:
%macro printit
proc print data=whywemustusethegoddamnmacor.itisjustatest;
run;
%mend printit;
Then next time you want to print, just use %printit. It is much easier, isn'
t it? |

发帖数: 7643 | 15 Say if you want to perform the same analyses on 10 variables, instead of
copying and pasting the same SAS procedures for 9 times with modifications,
you can write a macro and call the macro 10 times. Later on in case you want
to modify your analyses you can update the macro, instead of changing your
procedure 10 times. |

发帖数: 3154 | 16 In fact I just realized that, you can not write your own procedure (At least
not that easy). So if you want to implement any logic, you will have to use
macro. I came from other background so I thought SAS procedures are like
functions in other programming languages that you can write easily.

发帖数: 11146 | 27 You are right about that SAS procedure cannot be created by user. However, a
macro is just a bunch of procedures. It does not NECESSARILY help you
implement any logic.
I suggest you find a sample macro and a sample procedure and show them to
your LD. These two concepts are truly straightforward once you see examples,
but also impossible (I think) to explain just with words...
