In the case where the addressee is in the same country where the litter is sent, the inside address and the outside address on the envelope do not call for the name of the country. When writing or typing the inside address and indeed the outside address, it is safe to copy the address given in the incoming letter, avoiding abbreviations unless they appear in the incoming one. In most cases, the address follows the order of house number first, then street, town, state, postal code and finally the country name. And if one line in the address, say the mane of the firm, is too long in comparison with the other lines, divide the long line into two by indenting the second line two spaces.
      The salutation, which runs parallel to the letter body, is the complimentary greeting right before the body of the letter. The following salutations are frequently found in business letters:
      1¡¢¡°Dear Mr. ¡Á¡Á¡Á¡± is used when the sender is familiar with the person, or in answer to a letter received.
      2¡¢¡°Dear Sir(or Madam) ¡± is commonly used salutations to unintimate addressee. Showing respect rather than affection. While ¡°Dear Sir ¡±is usually used to address the executive officer of an institution, and ¡°Sir¡± is used to address a high ranking government official. ¡°Madam¡± can also be used for either the married or the unmarried woman.
      3¡¢¡°Dear Sirs (or Gentlemen)¡± is the most frequently used salutation to address a business firm or an organization when you have no idea whether the executives of the unit are made up of males or females. If you are aware that the executives are females, the corresponding salutation is ¡°Ladies¡±.
