using quotes in sas macro filename pipe

问题

I am using the following Macro that uses filename pipe. But get an error saying invalid option name "dir", etc. I suspect it could be due to the quotes while defining filename and pipe. I guess it recognizes it as an option. I tried to remove the quote, removing %bquote and having just the double quote, but still keep getting the errors.

I am using Windows, but will also be running it remotely on Linux. Any thoughts would be deeply appreciated.

%macro setprogvar(dateval);
  %global date;

  %let date=&dateval;

  %put &date;
  %put &dateval;

  %let filepath = %bquote("C:\Research\SASDataSets\bulk all data &date");

  filename CDR_Bulk pipe "dir &filepath /a:-d-h-s /b /s";

%mend setprogvar;

%setprogvar(20100331);

***LOG************

                                          -
                                          23

回答1:

The filepath Macro variable needs wrapping in double-quotes as it contains spaces. But as your string is double-quoted, you need double-double-quotes...

filename CDR_Bulk pipe "dir ""&filepath"" /a:-d-h-s /b /s";

回答2:

Try changing %bquote in your macro to %str().

%Str() works during macro compile time, and should mask the double quote marks.
