I just came across the following announcement of a product release that excited me a lot back when it was current on a page in the MacTech archives. For a long while, Heizer's collection of stacks was the holy grail for every budding programmer on the Mac. They published tools that did stuff you didn't think possible, and that helped you move gradually into "real" programming.
Heizer ships Double-XX
Heizer Software announced today that it is shipping Double-XX, a development tool for creating stand alone applications from XCMDs. Now, experienced HyperTalk scriptors and XCMD users can build applications for both custom and commercial use.
Double-XX uses XCMDs as building blocks. Developers "glue" them together with lines of HyperTalk to create stand alone applications. As the most recent addition to the Heizer Select Series (a collection of HyperCard-related development tools from Heizer Software), Double-XX provides the final link in the HyperTalk development chain.
To create an application, the HyperTalk developer simply selects resources (XCMDs, PICTs, ICONs, etc.); defines the menus; and decides on other determinants. Double-XX combines all the elements into a shell containing a very complete HyperTalk interpreter and a XCMD interface.
Depending on how the final application is configured, Double-XX will add between 75K and 150K of additional resources. A finished application will require a minimum of only 160K of RAM (plus the developerís requirements).
