Reference variable in filename

[Citrine10]

Hi there

i am unable to properly locate my file in my directory when I use a variable in the path

I am emptying the contents on the file by doing the below:

	filename csvfile 'C:/Logs/log.csv';
	data _null_;
  	file csvfile old;
	run;
	

i want to pass C:/AllLogs as a variable called &dir

%let dir = C:/Logs;
filename csvfile '&dir./log.csv';
	data _null_;
  	file csvfile old;
	run;	

The above way I do it does not work. Please advise where I am going wrong and how to resolve it. thank you

Macro variables have to be inside double quotes to be resolved.

filename csvfile "&dir./log.csv";
