ORCA/C 2.2.0

ORCA/C 2.2.0 is a new release of the ORCA/C compiler for the Apple IIGS. Major changes since ORCA/C 2.1.0 include:

• Added support for almost all language and library features required by the C17 standard
• Improved lint checks and debugging features to help detect errors
• New command-line options for pre-include files and C standard selection
• Improvements to generated code
• Auto-segmenting linker
• Hundreds of bug fixes
• And more

The ORCA/C manual has been fully updated to describe the new features. A readme file and detailed release notes are also available.

This is an update package designed to be installed on top of an existing copy of ORCA/C 2.1 or later. Instructions on applying the update are available here. Note that the disk image must be treated as a hard drive image or high-density floppy image. If you need to use an 800KB floppy, place the SHK file on it instead of using the disk image.

If you need a full copy of ORCA/C, you can get it as part of the Opus ][ collection sold by Juiced.GS.
