ΓòÉΓòÉΓòÉ 1. Help For MemStat ΓòÉΓòÉΓòÉ
MemStat Version 2.07 is a utility program which displays the current amount of
available memory, the size of the swap file and the amount of free space on the
swap drive under OS/2 2.x.
It has proven to be a useful tool, both in the test environment and in the
production environment.
For help on any selectable field, select the field and press F1 or select one
of the following options:
o About this release
o MemStat Display
o MemStat Menus
o MemStat Errors

ΓòÉΓòÉΓòÉ 3. MemStat Display ΓòÉΓòÉΓòÉ
The MemStat Display window contains up to three lines of information in this
release. Depending on how you have set up MemStat, the following information
may be displayed:
Available Memory
This is the value returned from the DosMemAvail function call and represents
the size of the largest consecutive block of free memory available when the
function was called. Note that this is memory available to 16-bit applications
and may not be meaningful for 32-bit applications running under OS/2 2.x.
Swap File Size
This is the physical size of the swap file, the location of which is taken from
the SWAPPATH parameter in CONFIG.SYS. Under OS/2 Version 2.x, the swap file
increases in size as your applications use memory and decreases in size as
physical memory becomes available so this value will go up and down as you
work.
Swap Disk Free Space
This value is the amount of free space left on the drive containing the swap
file. If this value goes too low, it is an indication that you may need to make
more space on your swap drive or move your swap file to another drive.
