DCAL Macros. * See "New Products" column in this issue for more information on Visual Software products and contact information. Don't confuse Keyboard Macros with Keyboard Interrupts or with DCAL Macros. Keyboard interrupts are the single-key "hot keys" that jump you to different menu locations in DataCAD; the X interrupt, for instance, takes you to the Object Snap menu, m to the Move menu, M to the Macros menu, etc. You find DCAL macros under the Macros menu. They are actually "mini-programs" written in the DCAL programming language and act as extensions to the functionality of DataCAD by adding features not found in the DataCAD menus. How Keyboard Macros Work When yo invoke a Keyboard Macro by holding down the ALT key and pressing one of the letter keys, DataCAD reads the file DCAD.MCR and executes the command sequence described on the line that begins with the letter that you pressed. In a standard setup, DataCAD locates this file in the \DCAD5\SUP directory. To understand the structure of a Keyboard Macro, let's take a look at the ALT+A keyboard macro in DCAD.MCR If you have a project you would like to share in The DataCAD as shipped with DataCAD 5.
