N do begin write (list [i] ); i end == i + 1 end; Example 2: Stock Update and Report Program A wholesaler keeps details of his stock on a magnetic storage file. Stock levels in the warehouse change as stock is bought, sold, returned, etc. The wholesaler wishes to use information regarding these transactions regularly both to update the stock file and to produce a printed report of stock and transaction information. It has already been decided to produce for this purpose a sequential file containing the transaction information.

1 STEPWISE REFINEMENT OF PROGRAMS Chapter I introduced the concept of designing programs by the method of stepwise refinement. In essence, we try to decompose a problem into a simple series of subproblems. Given a problem P, we try to discover a set of smaller problemsP1 ,P2 ,P3 , . . , such that solving firstP 1 , thenP2 and so on will be a solution to the original P. This approach is then applied to each of the subproblems P 1 , P 2 , P 3 , • .. , producing a set of sub-subproblems whose solutions taken together are a solution to P 1 • We continue this process until the problems are sufficiently small to be capable of solution directly.

N} declared in Algol by array a [ 1 : m, 1 : n] , is a two-dimensional array. Any number of subscripts or dimensions can be allowed to define array structures, but many programming languages provide for only one, two or three dimensions. The use of arrays is not restricted to mathematical applications. For instance, a directory with a fixed number of entries may be regarded as a one-dimensional array of entries e 1 , e 2 , . . , en. Indeed, any sequence with a fixed number of components may be regarded and implemented as a one-dimensional array.
