Mostly I would like to have back a small string produced after entering few integers...
anyway the functions is:
pw[j_Integer, nd_Integer, sl_Integer, oeo_Integer] :=
Style[StringJoin[" ",
Map[ctec[[# + 1]] &,
First[RealDigits[N[1/Prime[j*sl + oeo], (j*sl + oeo)*10*5],
Length[ctec], nd, -sl*oeo]]], " "], FontSize -> 25,
FontColor -> Red, Bold, Background -> Yellow]
where ctec is a list of all key-able characters in Latin-kb
