The HyperCard IIGS BugTracker stack was developed by Brendan Bellina to provide information about known bugs in HCGS, errors in the HCGS Script Language Guide, and also provide information about differences in Macintosh HyperCard 2.4.1 and HyperCard IIGS 1.1. Several documents are included in the stack that can be helpful to a HCGS developer. Several of those are also shared in this blog post. The stack is included in the HCGS Best Of 32 MG image available at the Silverwand Software site.
The following documents are included below:
