Greetings,

I would like to modify a data file on disk which has
the data enclosed in quotation marks.
A much-shortened example would be as follows:

File as stored on disk

"big","left","15","21.87","","0","smy"
"82","back","up","24","50","0","984"
"44","","up","symm"

I would like to read this file into Mathematica,
then (for example), place two "0"'s after "21.87" on the first line,
place three "0"'s after "50" on the second line, then
store the result back onto a file on disk giving

"big","left","15","21.87","0","0","","0","smy"
"82","back","up","24","50","0","0","0","0","984"
"44","","up","symm"

My stumbling block is mainly the quotation marks.

Thank you,
John C. Erb
