How to rename a text file with SAS in Windows XP?

Question

I have a process in SAS that creates .csv. I have another process in Python that waits until a file exists, and then something with that file. I want to make sure that the Python process does not start doing its job until SAS has finished writing the file.

I thought that I just got SAS.csv, and then rename the file after it is completed. Can I rename to SAS? Then the python process could just wait until the file is renamed.

EDIT: I accidentally posted this question twice, and then accidentally deleted both versions. Sorry about that.

Answer 5

How about a viewer watching a single small file instead of a large CSV file? This will be recorded in a single SAS write operation and will reduce the risk of starting a read before writing is performed.

 data _null_;
   file 'bigfile.csv' dsd ;
   set bigdata;
   put (_all_) (+0);
 run;
 data _null_;
   file 'bigfile.txt' ;
   put 'bigfile.csv written';
 run;
