    thanks

    Code:
    /* Reading from the script file */
    
    #include <stdio.h>
    #include <stdlib.h>
    #include <windows.h>
    #include <ctype.h>
    //#include <iostream>
    #include <string.h>
    
    int main()
    {
       FILE *myFile;
       char filename[20];
    
          
       /* Ask user to enter the filname including the format */
       printf( "Enter the script filename with the format. ie script.txt\n" );
       scanf( "&#37;s", filename  );
       
       /* Open filename for Reading (only) */
       myFile = fopen(filename, "r");
    		if (myFile == NULL) {
    			printf("ERROR! Unable to open your file.\n");   
                printf( "Closing file.......\n" );   
                //delay two second
                sleep (2000);
    			exit(-1);
       }    
       /* Open file success message */
            else {
                 printf( "The file %s is valid\n\n", filename );
    }
                 
                 
        char string[500];
        fgets (string , 500 , myFile);
        int strcmp( const char *str1, const char *str2 );
        
        char *tokenPtr;
        tokenPtr = strtok( string , " " );
          while ( tokenPtr != NULL ) { 
          printf( "%s\n", tokenPtr );
          tokenPtr = strtok( NULL, " " );
    }
    
    
         //EXE Crashes here
     if ( strcmp ( tokenPtr, "RESET" ) == 0 ){
          printf ("\n Resetting the motors.");
          //outportb(0x378, 0); 
          }
          
    
    
    
       getch();
       return 0;
    }

    Goto to FAQ
    look for fgets, fgetc, fread

    For example http://faq.cprogramming.com/cgi-bin/...&id=1043284392
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
