I figured out how to access and process the first token, but I want to check and see if the 2nd token is a digit. How do I access it? I have read that to access the 2nd token, another strtok() call must be used. I tried it and how I have my code doesn't work:

CODE

void lineEditor::processLine(char *newString)
{
  char *temp; // = NULL;

  strcpy(tempString, newString);
  temp = strtok(tempString, " ");

  if(isCommand(temp))
    {
      com = *temp;   //this part works
    }
  temp = strtok(NULL, tempString, " "); //this is where trouble starts
   if(isdigit(temp))
    {
      curLine = atoi(*temp);  //doesn't work
      cout << "CurLine in processLine is: " << curLine << endl; //just a test
      }
  else
    {
      insertLine(newString);
    }
  
}  



my isdigit() is wrong also. Any ideas?

trista, try this idea...

assume tempString = "trista greg john"
CODE
temp = strtok(tempString, " "); // temp = trista
temp = strtok(NULL, " "); // now temp = greg
