═══ 1. Introduction ═══ This program displays several items related to system resources, and updates the display once per second, providing it is given CPU time to do so. The items displayed are: Available Memory - The amount of system memory available, according to the DosMemAvail function. Under OS/2 1.x, this function supposedly reports the size of the largest single block of free memory, although some have said that with the MEMMOVE option turned on, that's the same as the total free memory. Under OS/2 2.0, the true amount of unused physical memory is reported, or 512K, whichever is larger. There is a new function under the 32-bit API which reports how much physical memory exists, how much is committed to the resident system and how much is free, but since this program is a 16-bit application, I don't have access to the function. Swap File Size - The current size of the system virtual memory swap file, SWAPPER.DAT. To locate the file, the file CONFIG.SYS is scanned for its SWAPPATH entry. That entry provides the full name of the swap-file's directory and indicates the minimum free space that must be left on the swap-file's disk drive. Available Swap Space - The amount of free disk space on the logical disk drive where the system swap file resides, less the mininum free space. This is how much more the swap file could expand, if necessary. Spool File Size - The amount of disk space consumed by spool files. CPU Load (%) - The approximate percentage of the CPU's available horsepower that's being used at the moment. It is averaged over the previous second. On my home system, which is a '286, the normal activity shows 8-10% when nothing except MEMSIZE and my clock are active. On my system at work, a 20MHz 386 running OS/2 2.0, the normal activity shows about 20%. I presume the extra overhead has to do with the swap-file optimizer. Drive X Free - The amount of free space on drive X. The help facility is active, as you've already seen, and those program commands that exist may be accessed via the window's system menu. The following commands are available: Save Defaults Reset Defaults Hide Controls Show Memory Free Show Swapfile Size Show Swapdisk Free Show Spoolfile Size Show CPU Load Show C: Free Space About In addition to those features already described, this program accepts commands from the OS/2 2.0 Font and Color Palette programs. I don't know of equivalent programs for OS/2 1.x, but from what I've learned, making such a thing should be no big deal. The basic palette function does not require OS/2 2.0 to make it work, since it uses the presentation parameter facility added under OS/2 1.2. ═══ 2. Save Defaults (Menu Option) ═══ When you select this menu option, the program saves its current position and the status of the Hide Controls option. The next time the program is started, it will be started with that position and with the controls hidden (or not) according to the saved state. The short-cut key for this command is F2. ═══ 3. Reset Defaults (Menu Option) ═══ Selecting this menu option will reset the program's font and color attributes to their default values. ═══ 4. Hide Controls (Menu Option) ═══ This menu option, when selected, will cause the program's frame controls (the system menu, the titlebar and the minimize button) to be hidden. This option can be toggled with a double-click on either mouse button. Also, since I saw it as very useful to be able to move the window while the controls were hidden, the window has been set up so that you can drag it with either mouse button. ═══ 5. Show Memory Free (Menu Option) ═══ Selecting this option will toggle whether or not the amount of system memory free is displayed. If the option is check-marked, the free memory is being displayed currently. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 6. Show Swapfile Size (Menu Option) ═══ Selecting this option will toggle whether or not the swap-file's current size is displayed. If the option is check-marked, the file size is being displayed currently. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 7. Show Swap Space Free (Menu Option) ═══ Selecting this option will toggle whether or not the available swap space is displayed. If the option is check-marked, the free space is being displayed at this time. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 8. Show Spoolfile Size (Menu Option) ═══ Selecting this option will toggle whether or not the amount of disk space consumed by the spooler is displayed. If the option is check-marked, the amount is being displayed at this time. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 9. Show CPU Load (Menu Option) ═══ Selecting this option will toggle whether or not the current CPU load is displayed. If the option is check-marked, the free space is being displayed at this time. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 10. About (Menu Option) ═══ This menu option, when selected, will cause the program's About dialog to be displayed. ═══ 11. About (Dialog) ═══ This dialog box displays the program name, icon and copyright information. To exit the dialog, press the ENTER key, the SPACE bar or the ESCAPE key. ═══ 12. Show C: Free Space (Menu Option) ═══ Selecting this option will toggle whether or not the free space on drive C: is displayed. If the option is check-marked, the free space is being displayed at this time. When the option's state is changed, the program window will automatically resize itself to suit the new number of displayed items. ═══ 13.
