   But if you/colleagues/readers/users can be relied upon to have   
   Windows, then very much that is difficult to write/read in   
   pure batch can be done much more readily by using CSCRIPT to   
   call a .VBS or .JS file.   
      
   AFAICS, not yet tried, one should be able to compose REGLARXP.JS   
   such that, in a batch file,   
      
         CSCRIPT //nologo REGLARXP.JS SRC "regexp" Sub DST   
      
   will always serve, where SRC & DST are environment variable   
   names, and REGLARXP.JS uses String.replace(Arg2, Arg3); the   
   RegExp for removing all non-ASCIIdigits would /\D+/g and Sub   
   is "".   
      
   But maybe it cannot work, because, if it did, the technique should already be   
   well-known here.
