+ *    FUNCTION NAME     : string_to_tokens
+ * 
+ *    FUNCTION TITLE    : Break a string into its tokens
+ * 
+ *    SYNOPSIS:
+ *
+ * int string_to_tokens(arg_string, arg_array, array_size, separator)
+ *    char *arg_string;
+ *    char *arg_array[];
+ *    int array_size;
+ *    char *separator;
+ * 
+ *    AUTHOR            : Richard Logan
+ *
+ *    DATE		: 10/94
+ *
+ *    INITIAL RELEASE   : UNICOS 7.0
+ * 
+ *    DESCRIPTION
+ * This function parses the string 'arg_string', placing pointers to
+ * the 'separator' separated tokens into the elements of 'arg_array'.
+ * The array is terminated with a null pointer.
+ * 'arg_array' must contains at least 'array_size' elements.
+ * Only the first 'array_size' minus one tokens will be placed into
+ * 'arg_array'.  If there are more than 'array_size'-1 tokens, the rest are
+ * ignored by this routine.
+ *
+ *    RETURN VALUE
+ * This function returns the number of 'separator' separated tokens that
+ * were found in 'arg_string'.
+ * If 'arg_array' or 'separator' is NULL or 'array_size' is less than 2, -1 is returned.
+ * 
+ *    WARNING
+ * This function uses strtok() to parse 'arg_string', and thus
+ * physically alters 'arg_string' by placing null characters where the
+ * separators originally were.
+ *
+ *
