Macro Variable as a part of filename

[arunrami]

Hello guys,

 I need use a value of macro variable as a part of the filename path in file name statement for dynamic environment. But when I tried the below code macro variable 'src' not resolved so am not getting expected result.

Can any one help to overcome this??

data Temp1;
	set Temp;
	start_time1=datepart(start_time);
	call symput('Newdate',start_time1);
	call symput('src',ZP_FL_NM);
run;

%let filrf=myfile;

%let rc=%sysfunc(filename(filrf,
	"/D:/Folder/src"));

%let fid=%sysfunc(fopen(&filrf));
%let Bytes=%sysfunc(finfo(&fid,File Size (bytes)));
%let Fname=%sysfunc(finfo(&fid,Filename));
%let fidc=%sysfunc(fclose(&fid));
%put &Bytes &Fname;

You have created the macro variable &src, and then you never use this macro variable anywhere. Perhaps that is the problem?

I am guessing you need:

%let rc=%sysfunc(filename(filrf,
	"/D:/Folder/&src."));

Or something along those lines.  But why have the macro code using macro variables created from a datastep?  Just use the datastep to open the file and get number of bytes, i.e. all but about two lines are totally unecessary:
 

data temp;
  fid=fopen();
  bytes=finfo(fid,File Size (bytes));
  Fname=finfo(fid,Filename);
  fidc=fclose(fid);
run;

And have a call symput if you need to at the end.
