  : Hello. How can I retrieve a particular character from a string?
  :
  : For example, in English, I will specify:
  :
  : set PHRASE as 'Pascal Programming'
  : get the fifth character from PHRASE
  :
  : then the result should be A because the fifth character is an A.
  :
  : How can I 'translate' this into Pascal? Thanks.

  A string is an 1-indexed array of chars. This means that you can get a the i-th character from string S using the following code:
  [code]
  ch := S[i];
  [/code]
  in your case it would be:
  [code]
  ch := Phrase[5];
  [/code]
