The aim of this stage of the course is to produce a suite of four related programs to City and Guilds 4240 standards. The student will have to design the logic and produce the code to a given programming specification, approved by City and Guilds, to satisfy the Applications Programming 4240 scheme. If possible the student will code, debug and test the solutions at home using a PC with approved compiler software. If this is not possible then the student will submit their coding on standard coding sheets so that our operators can type out and compile the programs. Results, syntax and logic error reports are returned to the student for amending and, in turn, returned for further processing. The completed project is further supplemented with supporting documentation such as structure and flow charts, file and print layout designs. The programs include: ~ Validating data from a file containing variable length record structures, and producing a detailed error report. This includes modulus check digit testing and use of single dimension tables ~ Sorting and printing a file that contains multiple record structures ~ Handling line sequential and indexed file using sequential and random access techniques to update, replace, create and reference various transaction and master files ~ Creating comprehensive test data to check all aspects of the program suite ~ Being able to identify and document program limitations |
