Author Description

This book's consistent use of structured programming provides a clear link to high-level languages. Proper structure is ensured by consistent naming of program structures. Assembler subroutines are linked to such high-level languages as Pascal, Basic, Fortran and C to facilitate the expansion of power for programming in high-level languages. Progaram design is first shown in flowchart form, pseudo-code, and assembler language; eventually flowcharts are eliminated, and pseudo-code appears as comments in the source code. Comprehensive coverage includes up-to-date technical topics and information often neglected or poorly presented elsewhere, such as early use of input and output in complete programs; comparison of different types of DOS file (Command and Executable) programs for better understanding of DOS files and programs; coverage of disk input/output operations to facilitate better understanding of disk file handling; and a library of useful, fully tested, subroutines and macros that can be used to create very useful pieces of software. Advanced topics introduced include writing macros and using conditioned assembly, detailed coverage of Microsoft's Micro Assembler MASM 5.0, passing subroutine parameters through the use of stack, video memory and graphics, and operations on multiple words.
