Although Forth has many advocates, a case could be made that it is not the easiest or most intuitive language for people to learn.
programs are organized into one or more 16-line "screens," another Forth convention. To edit "Cybercode," you must load each screen individually, edit the text it contains, and save it to disk before editing another screen; you can have only one screen's worth of code in memory at any one time. We strongly suggest the use of a RAM disk or a hard disk while editing Cybercode—otherwise the constant disk accesses will have you in the rubber room in short order.
The worst part of developing the program was the fact that I didn't have a hard drive at that point—just two floppy drives! Compiling the program was a nightmare of disk-swapping and trying to remember what files had been compiled and which hadn't. I didn't have a “make” utility at this point, which made life incredibly difficult.
