Verify file date windows

[Bottoni]

I developed a program that verify if exist a file in a directory. If the file exist the program start to run.

I've researched how to verify the modification date of the file(Windows) but I'm not finding anything about that.

For exemplo: if there is a file called TESTE.TXT in my directory and the modification date is the same as current date my program start to run.

Is that possible to do? 

SAS CODE:

%LET TESTFILE = "F:/teste/TESTE.TXT";            

%MACRO FINDIT;  
 
	%DO %UNTIL(%SYSFUNC(FILEEXIST(&TESTFILE)));

%END;

			PROC SQL;
			CREATE TABLE WORK.TESTE_II AS 
			SELECT *
			FROM WORK.TESTE;
			QUIT;	
		
%MEND;                                         
    
%FINDIT;

modified date is returned by the FINFO() function.
