Akos,

One method...

trimString[s_String] :=
  Module[{ss = s},
    While[First@Characters[ss] === " ", ss = StringDrop[ss, 1]];
    While[Last@Characters[ss] === " ", ss = StringDrop[ss, -1]];
    ss]

s = "   abcdefgh   ";
trimString[s] // FullForm
"abcdefgh"

I would appreciate if somebody could show me a simple way of trimming a
string. (I did it a hard way, but suspect an elegant solution.)

Trim(a_string): returns a copy of a string without leading and trailing
spaces.

thanks for your help,
