Programming with Macintosh Turbo PASCAL

The Turbo PASCAL software tools in this book enhance the internal 'toolbox' in the Macintosh computer by adding new commands to PASCAL in the form of library 'units', which can be compiled and stored on disks ahead of time. Chapters list the complete source code for several units, and include technical descriptions, instructions, and many programming examples. Tools are provided for building program shells, operating the mouse, creating windows, designing dialog boxes, and reading and writing disk files. For more advanced programming, there are instructions for directly accessing disk tracks, printing text and graphics, and adding text editing to programs, enabling readers to master the difficult art of object-oriented programming in PASCAL. Clear instructions are included together with helpful hints on managing Macintosh memory, a controversial topic and a recognized breeding ground for program bugs.
