Hi all,
I am using a macro to generate a non-fixed number of data-sets. I will have times when there are very few data-sets, and times when there are more (>100).
I want to transpose all these data-sets, and am therefore using a macro (%macro transp).
In the call-statement for the data-set-generating-macro the format is "z1.", which only works for up to 9 data-sets. And if I have only 9 data-sets, the %macro transpose works.
If I have 10 or more data-sets, and change the format in the call-statement to z2. or z3., then the %macro transpose does not work. This is because the count-step in the beginning used 1,2,3 etc. and not 01, 02, 03 etc. which is generated by using z2.
Is there a format I should use instead, that will use 1,2,3,4... and up to several hundreds, without the 0's in front?
If not, is there a way to adjust the count-part of the macro, to count with 0's infront?
Or, any other suggestions on how to make it work when I have 10 or more data-sets?
data _null_;
set list;
string = catt('%import_file(', dir, ', ', name,', ', catt('AAA', put(_n_, z1.)), ');');
call execute (string);
run;
%macro transp;
proc sql noprint;
select count(memname) into :num from dictionary.tables where libname='WORK' and memtype='DATA'
and memname eqt "AAA";
quit;
%DO no=1 %TO &num.;
proc transpose
data=AAA&no. out=BBB&no. (drop=_name_ _label_);
id A;
var B;
run;
%END;
%mend;
%transp
If you can have more than 100 data sets, why not just use Z3. always?
Then inside the macro
%DO no=1 %TO &num.;
%let zno = %sysfunc(putn(&no,z3.));
proc transpose data=AAA&zno. out=BBB&zno. (drop=_name_ _label_);

Many thanks! worked like a charm!
