Simply save a polynomial to a text file, with a symbol change I->%i and w/o NumberMarks

I must be really missing something here because I've tried many things on this link: How do I save a variable or function definition to a file? but still wind up with something I don't want.

I have the result of a Series[] in two variables - make it a 2-variable polynomial, and sometimes just in 1 variable, say after Normal[]... using lots of precision, and I just want to save it to a file. Probably to read it in as a string from some other CAS.

Here is the polynomial I want to save;

Thanks much!

PS Sorry, I would also like to exchange "I" with "%i".

UPDATE

For the replacement, I've got it working with this: Why can't I replace I with HoldPattern@I?

uno1 = TTS1 /. HoldPattern[Complex[r_, i_]] :> r + "%i"*i


as well as writing it to a file using;

uno2 = ToString[TraditionalForm[uno1]]

Only the first one, which when used with OpenWrite[] did not work for me... I put a$NumberMarks=False just before the OpenWrite[]... reference.wolfram.com/language/ref/\$NumberMarks.html I'll check the other too – nate May 14 '17 at 0:10
• I had in mind something like ToString[expr, InputForm, NumberMarks -> False, PageWidth -> Infinity]. How does that behave for you? – Mr.Wizard May 14 '17 at 0:20
• Well the above gives out weird things with FormBox, RowBox, and pre- and post-appended, with escaped punctuation, all wrapped in double quotes. But putting that through to OpenWrite, Write, Close gives the same result I've been having - with the narrowness back too though. – nate May 14 '17 at 0:29
• Would you please include the actual expression you wish to save, or a suitable example that exhibits the same behavior? – Mr.Wizard May 14 '17 at 0:37
