Alternative Development Environments

The following sections describe several useful alternative development environments for the Palm OS.

Assembler SDK (ASDK)

This SDK allows development of applications written in Motorola 68K assembler. It includes Pila (Pilot Assembler). To us this would be sheer agony, but apparently some developers enjoy writing applications in assembly language. To each their own poison. You certainly can’t beat the price—it’s free.

For more information, see Darren Massena’s web site (http://www.massena.com), which is an indispensable Palm developer resource in its own right.

Jump

This novel environment allows you to write your application in Java using a Palm class library and your favorite Java development environment. Jump then compiles the resulting Java .class files into Motorola 68K code. Jump includes a very small runtime library that provides crucial Java support like garbage collection.

The only disappointing aspect of Jump is that the Palm OS is not completely supported. For example, any calls that require a callback function as a parameter (such as LstSetDrawFunction and FrmSetEventHandler) won’t work.

This development environment is free, and source code is provided. Jump is the brainchild of Greg Hewgill; you can get it from http://www.hewgill.com.

CASL

This commercial package provides cross-platform support. You write an application once in the CASL language (a BASIC-like proprietary language) and then deploy it on Palm OS or on other operating ...
