   var fields,temp,handle,vararray
   readasctextfile('data.txt',fields)
   handle=btrvopen('phone.mxb',fields)
   while btrvresult=0
      btrvstepnext(vararray,handle)       ;<- Step to next file record
      writeln vararray[1] " " vararray[2]
   endwhile
   btrvclose(handle)

 Result Codes:
    9 - End of File
