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.

Form Sizer
~~~~~~~~~~
An OmniDesk Utility
by Richard G. Hallas
Form Sizer gives information about template files. When writing desktop
applications, it is useful to know how much memory to reserve for window
definitions, but this information is difficult to work out. However, Form
Sizer tells you exactly how much space is needed for both the windows
themselves and the data they contain.
Dragging a template file into the Form Sizer window (or onto the icon-bar
icon) results in information being displayed on each window in the template
file. This consists of the following:
(1) 'Global template block size' indicates the maximum size needed to hold
any window in the file. Note that this is NOT the size of all the windows
put together: rather, it is the size of the largest window in the file. The
reason for this is that it is not usually necessary to retain window
definitions once they have been created by your program. If you simply
reserve enough space for the largest window definition, you can then use the
same storage area for each window in turn as you create it, which is much
more economical than loading all the windows at once.
(2) 'Total indirected data size' indicates the total size of all indirected
data in all the windows. Note that this IS the total size of all indirected
data in the file, since your program does need to retain this data.
(3) For each window in the file, the following information is displayed in
the white area at the bottom of the window:
(a) Window identifier;
(b) Size of the window's definition;
(c) Size of the window's indirected data;
so you can reserve memory on a window-by-window basis if you prefer.
The 'Dec/Hex' button will switch the Form Sizer display between decimal and
hexadecimal numbers. This also affects the numeric contents of the template
statistics file available from the save window.
Clicking Menu over the Form Sizer window presents the main utility menu:
'Info' leads to a standard information window.
'Clear statistics' will clear out any template file currently loaded, and
release the memory it used.
'Window position' leads to a window which lets you determine where the Form
Sizer window appears on the screen. This corresponds to an invisible grid,
and when you change screen mode the window will snap to this grid. (This
feature can be disabled by clicking Adjust on the small window icon, which
makes it disappear.)
'Save statistics' lets you save out a text file of detailed information
about the loaded templates. This includes all the information shown in the
Form Sizer window, and in addition there is information about the type and
contents of all the icons in each window.
'Save settings' will save the screen location of the Form Sizer window,
along with the state of the 'Dec/Hex' button.
