What is 4th Dimension 1.x?

Until the debut of 4th Dimension, developers unwilling to construct a relational database from scratch were forced to choose between two application generators with very different personalities: Blyth Software's character based Omnis 3 Plus and Odesta’s icon-rich Double Helix. 4th Dimension encompasses the best of both these programs by combining the Macintosh user interface with an extremely powerful Pascal-like procedural language. 4th Dimension has all the power and flexibility required to develop custom applications capable of handling nearly any data-management task. In addition, the program lets you search, sort, and run procedures in the background when operating under MultiFinder.

4th Dimension provides separate environments for designing and using a database. The design environment allows you to create a database whose structure is visible (see “The Structure Window”). A file structure can contain up to 99 files, with each record containing up to 511 fields. To link files you simply draw lines connecting their icons. In the design mode you can also create procedures (programs) and custom menus, assign password protection, and build sophisticated form layouts using a MacDraw-like editor (see “Layout Design”). With these tools it’s easy to design a relational database with Mac-like features. It's possible to build hundreds of different forms with controls like buttons, check boxes, graphics, and scrollable areas.
