CodeMaster Library Window Management Demo The CodeMaster library for Micol Advanced BASIC GS is nearing completion. The demo file MAB.DEMO1.SYS16 is intended to show off the window management routines which constitute my modest contribution to Walter Hurt's effort. This library has lots of routines and will really help simplify development with MAB. It does lots of things, like all kinds of math, conversion of measurement units and string manipulation. But the library really shines as a tool for implementing the desktop interface with Micol Advanced BASIC. This demo shows that the library facilitates management of multiple windows with smooth scrolling and fast updates. The window scrolling and updates are supported by an assembly language routine, included with the CodeMaster Collection Library, that is linked into your Basic program automatically by the Micol Advanced BASIC linker. The assembly language routine uses a memory cache to store a bitmap image of the entire document for each window. When a window needs updating, Taskmaster calls the assembly language routine copy the appropriate portion of the image into the window. This technique is demonstrated in the Apple Computer source code demo program "Jiffy Windows" which was my inspiration for solving the problem of implementing smooth window scrolling in MAB. Here are some other interesting things about the demo: The demo uses the new System 5.0.2 quickdraw Fastport aware and Shadowing speedup techniques. I accomplished this by patching the Micol Basic Library. According to the Apple II GS toolbox Reference, Volume 3, these techniques speed up Quickdraw by 8-20%. The sys16 file was compacted and expressed using the new APW tools. Accordingly the file loads quickly via expressload under 5.0.2. If you have any questions concerning the library in general, please leave E-mail for CodeMaster. If you have any comments or questions about the demo or the window management techniques, please leave E-Mail for RMY. I would appreciate your comments and suggestions. Mike Yost 6/30/90
