- I can't see how a screen saver would work that way!
- ^^^^^^^^^^^^

- One suggestion for the speed time:
- After I tried Borland C++, I added the help system which is a TSR
- (I can't use the integrated environment). Having the TSR installed,
- the compilation speed was the half! One suggested that the TSR was
- taking memory and this made any memory-consommer program slower (since
- the program has to swap on disk when memory is full). The memory may
- be a major point if you save a graphics screen with some high definition card.
-
- BUT, I was and still am a Zortech user. And I did not notice the
- compiler slowdown in having the Zortech _old_ help system installed
- (I don't use the ZTC3.00r4 help which is from another dealer anyway and
- is bugged : maybe like the Windowsmaker, the licencer will sale you
- the not bugged version :-( ).
-
- To summarize, depending on how you implement it, you may have a different
- effect on speed. One reason is the duration of service (you could use
- an Assembler program to minimize time slice while waiting for screen
- to be saved). Another is the memory you are using. And there maybe some
- other reason (one nasty : if your program writes to some place in memory
- and this modify the DOS or the foreground program; but lets presume this is
- not the case).
-
- One last comment : Zortech has a TSR package included with the compiler.
- (It will allow _one_ entry by a special key combination and time slicing).
- Other commercial or shareware packages may exist.
