Dan's solution works excellently (thanks so much!).  I have made it a
function ("eFormatPrint"), and I combined it with an "f-format"
function (using PaddedForm) to give me a "gFormat" function with
string output like  [you need to view in a non-proportional font]:

For[i = 1, i <= Length[data], i++,
Print[ gFormatPrint[ data[[i]], 10, 3]  ]
]

    1.235
  1.235e7
1.235e-12
-1.235e-12
    2.000
   11.000

[With a fixed font, each value lines up right-justified in column 10}.

I've put these into a package "NumericalFileIO", useful for formatted
ASCII read and writes.
