It looks like that ^M in Mathematica is represented by \r. Thus, the following is one possibility to get rid of ^M's completely from within Mathematica : (use as: DosToUnix["thedosfiletobeconverted.m"] ): Options[DosToUnix]={CopyFile->False}; DosToUnix[file_String, opts___Rule]:=Block[{t}, t=ReadList[file,String]; t=Map[If[StringLength[#]===0,#,If[StringTake[#,-1]==="\r",StringDrop[#,-1],#]]&,t]; If[CopyFile/.{opts}/.Options[DosToUnix],CopyFile[file, file<>"old"]]; DeleteFile[file]; Do[WriteString[file,t[[i]],"\n"],{i,Length[t]}]; Close[file]]; Charles J.
