Many successful programs, including games such as Radzone and applications such as PowerPage, made use of this technique. Both through this (combined with CALL, PEEK and POKE) and the firmware's RSX system, it was easy to mix BASIC and assembly code, thereby speeding up programs by coding the slowest parts directly in machine code. The latter allowed for loading of raw screen data, thus providing easy picture showing. That was something unmatched by other computers of that era.Īlso there was simple interface for memory management, with MEMORY and LOAD commands. With the SOUND command, you could select channels, set envelopes, pitch, noise and volume. It had extensive sound commands, granting control of the AY-3-8912 via the firmware's volume and tone envelope system. Unlike the competing Commodore 64, it featured a comprehensive graphic capabilities with its PLOT, DRAW, PAPER, INK, PEN, BORDER and (in BASIC 1.1) FILL commands. The language benefited both from a clean, well-thought out implementation of the core language by Locomotive, and by the excellent firmware of the CPC, which lent most of its advanced features to the BASIC. Locomotive BASIC, was one of the best and fastest BASIC implementations of the era. 6 Other Basic Dialects available for the CPC.5.3.22 INSTR (‹searched string›, ‹searched for string›).5.1.7 CHAIN MERGE ‹file name›,DELETE ‹line number range›]].5.1.1 AFTER ‹time delay› GOSUB ‹line number›.Each module has a unique name and interfaces are used to combine these modules within a program. It is not necessary for a programmer who is working on one module to have knowledge about other modules. There will be very little or no dependency within various modules. Different modules are assigned to various programmers in a team so that each programmer has to work on a particular module that will perform certain operations. The modular programming approach was basically developed to maintain complex programs,ĭuring software development. Simplify collaboration for different modules Advantages of modular programming involve:ĭivision of big program into sub-programs The division of big programs into small modules increases the team work efficiency, maintainability and the quick debugging. Sometimes modules are identified as: sub-routines, macros or sub-programs. The key idea is to divide a gigantic program into small modules and each module has its own functionality, meaning the operations it has to perform. To manage these types of issues, modular programming comes into existence. Many software programs consist of thousands of lines of code it is quite challenging to analyze any semantic and syntactical errors within it. Modular programming is an approach to software development in which various independ ent codes are implemented in a way that the operations they are going to perform will be collaborated easily and can be reused. Modules are generally interoperable so that they can interact with other modules or functions within a program without a programmer. Interoperability: It is the ability of a program or function to communicate with other functions to achieve higher efficiency. This will be very helpful while developing a complex software program on which multiple teams work, with different operating systems. Portability: Modules allow a code that is developed in one environment with a specific operating system, to be ported to a new platform without developing it again. One can reuse the same code with a different approach within a program. Modules can help the programmers avoid typing or copying/pasting a single code, multiple times in a program. Reusability: While developing enterprise-level software, modules are implemented to make it simple, easy to understand and can be used over and over, again. During implementation or debugging, it is quite simple to access or test a single module in one go, rather than accessing the whole software program. These modules are then implemented within a big program with the help of interfaces. Programmers have to focus on a single area of code, not on thousands of lines of code. Easy to Use: Modules make complex software simple to use and check.
