MACRO help

Hi, I am trying to run a MACRO step to output multiple datasets based on the dates. However, I can't seem to figure out how to mend the dates and create unique table names:

%macro duo(rptmth);
proc sql;
create table P&rptmth as select * from dataset
where reportdate GE intnx('month',&rptmth.d,-12) and reportdate LT intnx('month',&rptmth.d,1)
quit;
%mend duo;
%duo('01Sep2015');
%duo('01May2015');

Thanks,

Jeff

If you were to include this statement as part of your program, you would immediately recognize that it won't work:

create table P'01Sep2015' as ...

That's all macro langauge is doing ... substituting text in order to generate the programming statements. While you do require quotes for the date literals, you can't include them as part of the table names. Instead, try calling the macro without quotes:

%duo (01Sep2015)

To make that work, you would have to add quotes for the date literals:

%macro duo(rptmth);
proc sql;
create table P&rptmth as select * from dataset
where reportdate GE intnx('month',"&rptmth."d,-12) and reportdate LT intnx('month',"&rptmth."d,1)
quit;
%mend duo;

Use double quotes, not single quotes, around macro variable references. That's a requirement to permit macro language to resolve the values.
