lets developers write Smalltalk applications for Palm Powered™ handhelds,
and other small devices.
Smalltalk consists of an integrated development environment (IDE)
which runs on a variety of platforms (Windows, MacOS, Linux, OS/2,
others). It includes a cross-compiler that can generate PalmOS "executable"
(.PRC) files from Smalltalk source code.
Smalltalk makes it easy to do object-oriented development for Palm
Powered handhelds. You have the full power of Smalltalk along with
a complete class library. Best of all, Pocket Smalltalk creates
