Hi all,

  command in the following codesnip. Has someone a explanition for this ?
Thanks in advance.

codesnip:
[...]
bool isLine2Skip(const string& s) {
  return ( (s[0] == ';') || // Comment
           (s[0] == ' ') || // Space
            s.empty() );    // Empty String 
} // bool isLine2Skip

bool ReadDataFile(const string& s)
{
  try {
    ifstream in(s.c_str());
    if (!in) throw ERR_FILE_OPEN;
    
    string line;

    do {
      getline(in, line);
    } while (isLine2Skip(line));
    pf.MeanS = atof(line.c_str());
