This archive contains three of my many packages of HyperCard XCMDs and XFCNs. “File Utilities” includes functions for doing things with files and directories, including getting/setting info and reading/writing files. “Resource Utilities” has functions for manipulating resources and memory blocks. “Utilities” contains functions that don’t fit into any other category.
Most of these externals, particularly the file and resource ones, are very low-level, and generally let you make direct calls to the underlying Macintosh system services. This makes them powerful and flexible, but it can also make them dangerous to use. To make proper use of them, you really need to be familiar with the appropriate volumes of the “Inside Macintosh” programming documentation.
Sorry I haven’t provided examples to show you how to use them. If you look around the net, you may see them pop up in some of my other stacks. For example, the current release of my Sound Utilities package makes use of the resource externals in the demo stacks.
Licensing: you may notice that each external has, embedded at the front, a message saying it “may be copied and distributed, but not for direct commercial gain”. You are free to use these externals in your own stacks and redistribute them, provided you do not ask money for them (I do ask that you mention me in your credits). Any other use requires my permission.
