ERROR 73-322

Miracle — Mon, 20 Jul 2020 15:52:18 GMT

Dear Everyone,
I wanted to add prefix "o" to all the variables in foo.
But I don't understand what is missing.
Can anyone point me out please?
Thanks in advance.
After the last iteration, this is what SAS log shows.

SYMBOLGEN:  Macro variable VAR86 resolves to val86
MLOGIC(ADDPREFIX):  %DO loop index variable I is now 87; loop will not iterate again.
NOTE: Line generated by the invoked macro "ADDPREFIX".
10937    quit; run;
             -
             73
             76

The error it gives are
ERROR 73-322: Expecting an =.

ERROR 76-322: Syntax error, statement will be ignored.

%macro addprefix(add=);
proc datasets library=work;
modify foo;
rename %do i=1 %to &num_vars.; &&var&i=&add.&&var&i. %end;
quit;
run;
%mend addprefix;
%addprefix(add=o);

Hello,

I think you miss a semi-colon for the rename statement (after %end;).

Thanks @gamotte for your quick response.

Why is another ; needed?

You're welcome.
One ';' for the %end (i.e. for the macro instruction %do; ... %end;) and another for the rename statement.
