  46. Have you checked the return code of the chdir() function. It may not
  47. be changing into the directory. ie 
  48.  
  49. main( int argc, char * argv[])
  50. {
  51.     char * string = "Error Message";
  52.  
  53.     clrscr();
  54.  
  55.     if ( chdir("h:\data") == -1)
  56.     {
  57.         printf("Error changing to .\n");
  58.         perror(string);
  59.     }
  60.     else
  61.     {
  62.         system("hi.bat");
  63.         getch();
  64.     }
  65. }
  66.  
  67. Unfortunat;y there is no way to determine the exit status of the
  68. program run using system(). Use one of the spawn functions if an exit
  69. status is required.
  70.  
  71. Hope this is of use.
