1. Introduction OS-9 Pascal from Microware is a powerful programming suite. Compared to Basic09, what it lacks in ease of use and graphics capabilities is compensated by its speed. Typical OS-9 Pascal programs execute up to 10 times faster than Basic09 counterparts. The enclosed Sieve of Erastothenes benchmark runs 9 times faster as assembled Pascal (31 seconds) compared to the Basic09 version (over 4 minutes). On my iMac G5/2 gHz under MacMESS/NitrOS-9, it runs in 12 seconds. However, Pascal adheres to strict programming rules, and requires diligent attention to programming detail. Those who have used C can attest to its forgiveness: Many programs will compile successfully, yet fail to do the expected job! Debugging C can be quite a chore. So there will be times when OS-9 Pascal will be a better choice for programming, particularly if you want to learn a highly portable and contemporary structured programming language. In addition, with the use of PascalS, PCODE programs over 8 Mb can be run on the Color Computer 3. Quick Pascal will makes OS-9 Pascal much easier to use. Pascal is commonly used to teach programming fundamentals throughout the world, and is used in private industry as well. OS-9 Pascal strictly adheres to ISO standard (7185.1 Level 0), and therefore will port easily to other ISO-compliant Pascal systems (with noted exceptions contained within the OS-9 Pascal Manual).
