+ * Description:
+ * val() converts the value represented in the string S to a numerical
+ * value, and stores this value in the variable V, which can be of type
+ * Longint, Real and Byte. If the conversion isn't succesfull, then the
+ * parameter Code contains the index of the character in S which
+ * prevented the conversion. The string S is allowed to contain spaces
+ * in the beginning.
+ *
+ * The string S can contain a number in decimal, hexadecimal, binary or
+ * octal format, as described in the language reference.
+ *
+ * Errors:
+ * If the conversion doesn¡Çt succeed, the value of Code indicates the
+ * position where the conversion went wrong.
+ *
