Hi

I have two macro variable, one is &ab the other is &cd. I want to insert
these two macro variables into one variable name like: flp&ab&cd.

But it seems this method does not work. Could you help me figure out what's
the format I should use?

Thank you very much

Jane

Jane ,

Not sure where your problem is since you didnt provide any code nor log but
here is a couple of examples:

%Let AB = 123 ;
%Let CD = ABC ;
%Let FLP&AB&CD = FLP&AB&CD ;
%Put FLP&AB&CD = &&&FLP&AB&CD ;

Data _Null_ ;
FLP&AB&CD = "FLP&AB&CD" ;
Put FLP&AB&CD= ;
Run ;

Hi Jane,



%let ab=apple;
%let cd=cherry;
%let abcd=flp&ab&cd;

%put _global_;

If you are looking for a period in your text
then you need two of them.

%let abcd=flp&ab&cd..;
%put &abcd;

The reason is that you may have text following
the macro variable reference such as:

%let abcd=flp&abcherry;
%put &abcd;

This does not work because the computer cannot
distinguish "ab" from "abc" or "abch" or "abcherry",
so SAS uses a period to formally give you a way
to tell SAS where the macro name stops and the
text begins, such as:

%let abcd=flp&ab.cherry;
%put &abcd;

So the first period after a macro variable reference
essentially gets gobbled up.  Therefore if you really
want a period character at that same location you just
have to add a second one that will be left alone as
text since the first period gets gobbled up.

%let abcd=flp&ab..cherry;
%put &abcd;




Hope this is helpful.

Thanks Toby and Mark

I found out why I can not simply insert two macro variables, since there two
macro variables were from two different macro procedures. I used them in
another macro procedure. It seemed I should define them as global macro
variables.

Do you think am I right?

Thanks
Jane

Hi Jane,

If things are as you say, you are correct.
Macro variables created inside other macros
are not available outside of those macros.
Indeed they are local to those macros. Yes
if you make them global
    %global myvar;
in those macro routines, then the will be
available outside of those macros.

You can place the %GLOBAL statement
for them inside or outside of those routines.

e.g.



%macro xxx;
    %global aaa;
    %let aaa=hello;
    %put inside macro is &aaa;
%mend;
%xxx;
%put outside is &aaa;


%global bbb;
%macro yyy;
    %let bbb=hello;
    %put inside macro is &bbb;
%mend;
%yyy;
%put outside is &bbb;





Hope this is helpful.
