'
' Determine transaction type 
PRINT "Type a 'D' for a deposit or a 'C' for a check"

'
IF TYPE$ = "D" THEN
  ' Process a deposit. 
  PRINT "What is the deposit amount"
  INPUT DEPOSIT
  LET BALANCE = BALANCE + DEPOSIT
ELSE
  ' Process a check. 
  PRINT "What is the check amount"
  INPUT CHECK
  LET BALANCE = BALANCE - CHECK
END IF
'
' Print the new balance. 
PRINT "The new balance is", BALANCE
'
END

QUESTION 14:

Study the program and mentally review how the "big problem" was broken into smaller tasks, and how those tasks were implemented. Notice how the indenting and the comments help show this. Would the program be as clear with no comments and no indenting?
