The basic idea of stepwise refinement may be described in several different ways (a) decompose a problem into a sequence of subproblems (b) refine each statement into several statements with increasing detail (c) expand what is to be done into a specification of how it is to be done. 2. Make the refinement steps small enough so as to be comprehensible and therefore checkable for correctness. 3. At each step bear in mind the feasibility of the decomposition. 4. After each step, check for errors before proceeding to the next.
An input text consists of one or more words, separated from each other by one or more spaces and terminated by zero or more spaces followed by a point. With the character valued function RNC (Read Next Character) the input text should be read from and including the first letter of the first word up to and including the terminating point. An output text has to be produced, using the primitive PNC(x) (Print Next Character) with a char<1cter valued parameter, with the following properties (a) successive words have to be separated by a single space (b) the last word has to be followed by a single point (c) when we number the words 0, 1, 2, 3, ...
PIC X(20). PIC 99. PIC 99. PIC 99. PIC 9(6). could be defmed with more precision by type orderrec = record orderno : 0 .. 9999; description : array [1 .. 20] of char; thedate : record theyear : 0 .. 99; themonth: 1 .. 12; theday : 1 .. 31 end; : 0 .. 999999 orderval end Notice that in this example and generally we may use any simple structured type as record components. imagpart assigns the imagpart of x to the realpart of y. For obvious reasons this method of denoting record type components is known as the 'dot-notation'.
