Memory info Alt + F5
This command lists the memory-resident programs which are
currently occupying system memory.
The Address column is the segment address of the start of
the program's memory block, in hexadecimal.
The Blocks identifies how many blocks of memory are used by
the program.
The Size column lists the sum of the sizes of all memory
blocks allocated by the program.
The Program column identifies the program if its name is
available, or specifies one of the DOS system area, Unknown
owner, or Free memory.
Hooked Vectors lists the interrupt vectors which point into
memory owned by this program.
The resident programs which can be removed are marked by '.'.

Notes:
. TSR stands for Terminate and Stay Resident. This type
of program leaves all or part of itself in memory
when it returns control to DOS.
. Often a TSR with a lower address controls interrupt
not listed here, but some other TSR (loaded after the
first) has seized primary control of that interrupt.
Most TSRs are careful enough to pass control to the
previous owner.
. If a TSR was removed from memory, it often leaves a
large block of unused memory in low RAM. That memory
might be used by a smaller program, but it is not
available for a larger program. The solution is to
load such a TSR last, and remove it before loading
any other TSR.
. You can remove TSRs which were loaded after loading
the Commander. To install the resident programs
automatically make a batch file, for example auto.bat,
including these TSRs and type it in command line when
the Commander starts:
VC auto.bat
