Once you "pick up" a page of text, however, you still need a good editor to manipulate it. I would agree that an editor for that environment should be page or document oriented. On a different tack, here's a quote from "Perceptual Components of Computer Displays", Ralph Haber and Leland Wilkinson, May '82 IEEE Computer Graphics and Applications: A flowchart interpreter should have several convenience features. As in the execution time displays of the Harpy speech recognition program, flow of control during execution ought to be highlighted so that the programmer can follow it easily. Breakpoints should be under light-pen control so that a programmer can catch a bug "on the fly." In addition, the user should be able to control the detail in the display. At the highest level, an entire program could be displayed on screen as a set of procedures. The user could then choose to zoom any area of the screen down to blocks, subroutines, macros, or single instructions. Steps in this direction have already been taken. Cross assemblers, compilers, and programs that check syntax and flow of control already perform many of the required tasks. -- Ken Laws -------
