Apple Power Macintosh (7100 Series) - Manual (Page 65)

Using Power Macintosh application programs
Your Power Macintosh is compatible with most application programs
intended for use with Macintosh computers. But certain programs are
designed especially for Power Macintosh computers. (These are sometimes
called “native” applications.) You’ll find that these programs take best
advantage of your computer’s speed.
Special memory requirements
Some Power Macintosh programs may be slightly larger than other programs
and may take up more memory. If you find that you are running out of
memory when you use your Power Macintosh programs, you can use space
on your computer’s hard disk as additional memory. For instructions on how
to use hard disk space as memory, see the “Memory” topic of Macintosh
Guide, available in the Guide (h) menu.
You can also add more memory to your computer, as described in “Expanding
Memory” in Chapter 3.
Shared libraries
Power Macintosh programs use special files called shared libraries. These files
help Power Macintosh programs to run more efficiently, and can be used by
more than one Power Macintosh program simultaneously. Any necessary
shared libraries are installed automatically in the System Folder when you
install Power Macintosh programs.
If a Power Macintosh program requires a shared library and there is not
enough memory available for the shared library, you’ll see a message that
the program could not be opened because of insufficient system memory. If
this happens, see the “Memory” topic of Macintosh Guide, available in the
Guide (h) menu, for instructions on turning on virtual memory.
If a required shared library is missing, you’ll see a message that the program
could not be opened because the shared library could not be found. If this
happens, follow the directions that came with your program to reinstall the
program. If the shared library is still missing, contact the program’s
manufacturer for assistance.
