Error while Reading multiple files with filevar statement - Invalid physical name

[Babloo]

I'm trying to read the series of files from .txt file via SAS macros. However I could not succeed for unknown reason. I'm puzzled where to resolve this error. Could someone check that my infile statement is do loops are having any issue?

 Your help is greatly appreciated

My code looks like,

data log.output_file ;
  infile "&path/output_file.txt" firstobs=2 truncover ;
  input fname $400. ;
run;

%macro log_analysis;
%let filedate=%sysfunc(putn("&sysdate9"d-1,yymmdd10.));
%put &filedate;
data log.log_analysis;
set log.output_file;
filename=fname;
length fname $400;
infile dummy dsd truncover FILEVAR = fname END = end_of_file LRECL=32000;
DO WHILE (not end_of_file);
input var : $ 3000.;
/*filename=fname;*/
var1 = _infile_;
if var1 = :'201' then do;
Date_TimeStamp= scan(var1,1," ");
Status = scan(var1,2," ");
Processid = scan(var1,3," ");
userid = scan(var1,4," ");
Details = scan(var1,-1,'-');
output;
end;
end;
drop var var1;
run;
%mend log_analysis;

data _null_;
  set log.output_file;
  if fname =: '/usr/sas/sas_config/Lev1/SASApp/StoredProcessServer/Logs/SASApp_STPServer' then call execute ('%log_analysis;');
else put 'no log files';
run;

First datastep to create a dataset log.output_file was succeed and it has 3 observations as follows.

fname
/usr/sas/sas_config/Lev1/SASApp/StoredProcessServer/Logs/SASApp_STPServer_2015-09-25_tmptcmsaslva2_19142.log
/usr/sas/sas_config/Lev1/SASApp/StoredProcessServer/Logs/SASApp_STPServer_2015-09-25_tmptcmsaslva2_18208.log

When I run my code I got error as follows,

NOTE: CALL EXECUTE generated line.

The 3rd observation in log.output_file is empty (fname='') ?

Try:

data log.output_file ;

infile "&path/output_file.txt" firstobs=2 truncover lrecl=400;

input fname $400.;   

if fname ne '';

run;

When I recreate the .txt file, error did not appears.
