In some languages "S" * n returns a string of n "S"s...

is there a built in to do this in Mathematica - I can't find it in the
docs..

Again, thanks

Chris

There is no built in function to do this as far as I know. But
it is a simple matter to create one. For example

In[6]:= strTimes[x_String, n_Integer] := Nest[# <> x &, "", n]

In[7]:= strTimes["S", 6]

Out[7]= SSSSSS

In[8]:= StringLength[%]

Out[8]= 6

To my knowledge, there isn't. But it is trivial to implement:

Clear[stringRepeat];
stringRepeat[s_String, n_Integer?Positive] :=
StringJoin @@ Table[s, {n}]

In[1]:=
stringRepeat["S", 10]

Out[1]= "SSSSSSSSSS"

Leonid

function to the use simplier. E.g a "a" followed by 10 "b"'s:
