Supressing Null in a Do-loop












1












$begingroup$


I'm trying write a Do-loop that creates batch files that run .exe files with input parameters. I have to rename to *.bat since Export doesn't like outputting batch files. The output produces batch files with the text of the form:



Analyze.exe Calibration_# Null [input parameters]


which doesn't run due to the Null.



How would I go about suppressing the Null in this case?



I'd also like to change input parameters, but it seems that Do likes inserting Null. I've tried DeleteCases Null, but it's baked into the string, so that doesn't work. 



Do[

  shotN = n;



  DeleteFile[{"1.bat", "2.bat"}];

  Export["1.txt", 

    StringReplace[

      "Analyze1.exe Calibration_xx [input parameters]",  

      "xx" -> ToString[shotN]]];



  Export["2.txt", 

    StringReplace[

     "Analyze2.exe Calibration_xx [input parameters]", 

     "xx" -> ToString[shotN]]];



 RenameFile["1.txt", "1.bat"];

 RenameFile["2.txt", "2.bat"];



 Run["1.bat"]

 Run["2.bat"]



 , {n, 1, 10}]





export

    Try Export["filename.bat", <<string>>, "Text"]. That should get you rid of the need for Rename. And separate the Runs by semicoli (;).

The Runs need to be separated by semicoli. Moreover, you may use the export filter "Text" independent of the file type. This removes the need (i) to delete potentially preexistent files and (ii) to rename the files after export. Also StringJoin (<>) might become your friend.



Do[

 Export[

  "1.bat", 

  "Analyze1.exe Calibration_" <> ToString[n] <> " [input parameters]",

  "Text"];

 Export[

  "2.bat", 

  "Analyze2.exe Calibration_" <> ToString[n] <> " [input parameters]",

  "Text"];

 Run["1.bat"];

 Run["2.bat"];

 , {n, 1, 10}]
