    Read Array pro!!Plz help!!

    Hi all, i got trouble reading array file

    sample file to be read:

    ---------------------------------
    START 3
    . 000 2 100 . 000 . 000
    0 100 1 050 . 000 . 000
    . 000 . 000 . 000 . 000
    . 000 . 000 . 000 . 000
    END
    START 2
    . 000 2 100 . 000 . 000
    0 100 1 050 . 000 . 000
    . 000 . 000 . 000 . 000
    . 000 . 000 . 000 . 000
    END
    ----------------------------------
    The problem is when I try to read char, I just can get space
    it is weird and hope somebody can help me out
    thanx in advance!!

    my code:
    Code:
    int main()
    {
      char label[6];                     //String to read in the START/IN label
      char descriptor;                          //Char to read in the descriptor
      int descriptorVal;                        //Int to read in the descriptor's value
      int numTurns;                             //Number of turns read from the input file 
      int numRows;                              //Number of rows in the matrix
      int numCols;                              //Number of columns in the matrix
      int tempNumCols;                          //Copy of 'numCols' 
      char descriptorArray[MAXDIM][MAXDIM];  //Matrix to hold the descriptor map
      int valueArray[MAXDIM][MAXDIM];           //Matrix to hold the descriptor values
      int x, y, index;
      FILE *infile;
    
      infile = fopen("a.dat","r");
    	if (infile == NULL)
    	{
    			printf("Error. File does not exist.\n"
     					"Terminating Program.\n\n\n");
    	}
    	else
    	{
    		// Gather the input and play the game as long as there is input to process: 
    		while(fscanf(infile, "%s", &label) != EOF && !strcmp(label, "START"))  
    		{
    			// Reinitialize re-used variables to allow them to be re-used if necessary:
    			numRows = 0;
    			numCols = 0;
    			tempNumCols = 0;

    				}
    
    			// Get the number of turns:
    			fscanf(infile, "%d", &numTurns);
    	
    			// Get the map, partitioning the descriptor and value into separate arrays:
    			for(index = 0; index < MAXDIM; index++)
    			{		
            //As long as we are not at the end, get the next descriptor/value pair:
    				while(!foundEND(infile))
    				{
    				//If we found a descriptor/value pair, store them in the appropriate arrays
    					if(fscanf(infile, "%c ", &descriptor) && fscanf(infile, "%d ", &descriptorVal)) 
    					{  
    						descriptorArray[numRows][tempNumCols] = descriptor;
    						valueArray[numRows][tempNumCols] = descriptorVal;
    
    						numCols++;

    That's because a 'space' is a 'char'.

    Hope is the first step on the road to disappointment.
