your Macintosh memory can become fragmented so that you cannot open a large
program. If you suspect that this problem is the cause of memory shortages
when using MultiFinder, try quitting all the programs you have open, then
restarting the ones you need.
Changing the memory allocation for a program
When you start an application program, the program automatically tells your
system software how much RAM it needs. But on rare occasions (for example, if
you see frequent messages that there is not enough memory for the program),
the program may need a larger memory allocation. You allocate additional
memory by adjusting the program's memory size in the Info window.
The program must not be in use when you reallocate memory.
Follow these steps to change a program's memory allocation:
1. While on the desktop, select the program's icon.
2. Choose Get Info from the File menu.
The Info window appears.
3. Drag across the number in the small box at the bottom of the window to
select it.
4. Type a new number for the amount of memory you want to allocate.
5. Close the Info window to complete the allocation.
Tab key shortcut: You can also select the number in the small box at the
bottom of the window by pressing the Tab key.
!! IMPORTANT: Do not set the memory allocation for a program to a size that
is smaller than the manufacturer's suggested size. This could cause the
program to function improperly or not at all. !!
Adjusting the RAM cache
The number of programs and desk accessories you can use at the same time in
MultiFinder is also affected by the size of the RAM cache, if you are using
it.
The RAM cache is a specified reserve of memory that helps programs work more
quickly and efficiently. The memory assigned to the RAM cache is not
available to MultiFinder, however.
MultiFinder permits a maximum RAM cache of 384 kilobytes (K) for each
megabyte of RAM in the computer. If your system's RAM cache is larger than
that limit, MultiFinder automatically reduces the cache to the limit.
To maximize MultiFinder's ability to handle multiple programs, turning off
the RAM cache or setting it to a very small size -- such as 32K -- is
advisable. (The RAM cache is preset to Off, so if you have not turned it on,
you do not need to worry about resetting it.)
You set the RAM cache in the General section of the Control Panel.
