  6.   * CALCULATE STOCK PROFIT
  7.   *_______________________________________________________________
  8.   * This program computes the profit or loss from selling
  9.   * shares of stock. It uses a function to calculate the
  10.   * profit based on the purchase price, selling price,
  11.   * and commissions paid.
  12.   *
  13.   * Computation is based on the formula:
  14.   * Profit = (Shares * Selling Price - Selling Commission)
  15.   *        - (Shares * Purchase Price + Purchase Commission)
  16.   *_______________________________________________________________
  17.   * INPUT
  18.   *   shares          : Number of shares of stock
  19.   *   purchasePrice   : Purchase price per share
  20.   *   purchaseComm    : Purchase commission paid
  21.   *   sellingPrice    : Selling price per share
  22.   *   sellingComm     : Selling commission paid
  23.   *
  24.   * OUTPUT
  25.   *   profit          : Profit or loss from the stock sale
