Question: What is business letter of instruction? 

Answer: Just what the name implies.  A business letter is a no-nonsense letter with certain basic formalities of style.  An instruction in a business letter would undoubtedly be a step-by-step list of exactly what to do, in detail.  Like this:\n\n1.  Make three copies of the enclosed document.  Punch original and all copies with a two-hole punch along the top.\n2.  Write a filing fee check in the amount of $185.00 made out to "clerk of the court."\n3.  Take the above to the court clerk's office at room 102 of the county building.  It is open from 8:30 a.m. to 5:00 p.m.\n4.  Hand the original and all copies to the clerk at the counter.  It may be helpful to point out which is the original.  Hand her the check as well.\n5.  She will return the copies to you stamped "filed" with the date.\n6.  Keep one for your reference and return the other two to our office.  We will see that they are served on the defendant.\n\nIf I was typing the above on a word processor, I would make the numbered paragraphs indented, and put an extra space between each paragraph.
