!FreeMem/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

FreeMem 1.03 !Help file � Liquid Silicon 1992, 1993 FreeMem is public domain, all files to be kept together and unaltered. FreeMem is a module application which displays the amount of free application memory on the icon bar. This is the total of the Next and Free slots. It has been written as a module so that it uses the least amount of memory possible (under 3K) and runs as quickly as possible, so as not to interfere with the machine's use. There are two options available, selected by toggling 'Quick' or 'Font' in the icon bar menu. With Quick ticked, FreeMem detects changes in the following : Applications starting and quitting; Mode changes; WimpSlot changes (eg when loading documents into DTP packages etc). Increases to the font cache and other system memory allocation entries will not register (except for RAM disc creation or removal and the screen memory on mode changes). To update the display to take changes of any of these into account, click Select on the FreeMem icon on the icon bar. Alternatively, deselect the Quick menu option. This will constantly update the amount of free memory displayed, no matter what changes occur (useful when printing and when using large numbers of fonts). Because this uses the null reason code in the Wimp polling loop, it uses a little more processor time than with the Quick option on, although it will usually not be noticed. Clicking on 'Font' will toggle the use of the Homerton.Medium font for the display, rather than the system font. This is best used with hi-res modes on SVGA or multisync monitors as normal monitors lack enough definition. If you are using RISC OS 3, the icon will always be next to the palette, otherwise it will reappear to the left of the other application icons. FreeMem will also save its pathname into the desktop boot file in RISC OS 3. By default, the Font and Quick options are off. Placing an 'F' or a 'Q' at the end of the !Run file in any order will toggle the relevant option. Some examples : RMEnsure FreeMem 1.03 RMRun <FreeMem$Dir>.!RunImage F RMEnsure FreeMem 1.03 RMRun <FreeMem$Dir>.!RunImage qf RMEnsure FreeMem 1.03 RMRun <FreeMem$Dir>.!RunImage f Q These can also be used to run FreeMem, as the actual application is not needed (apart from the sprite file) Clicking Adjust on the icon will display the current time for a few seconds and then redisplay the memory. Known problems : ---------------- Using the Font option can sometimes display the wrong aspect ratio for the font when moving to another mode. Deselect and then reselect the font option to cure this.
