TrueType fonts consist of two files each, with extensions of .FOT and .TTF.
The .FOT file is actually a Windows DLL that contains, among other
things, the path name for the TTF file, which contains the actual font. The
retail version of Windows comes with a dozen or so TrueType fonts, includĆ
ing Times New Roman, Arial, and Wingdings. The minimal PEN*KEY
6000 Series Computer configuration contains
no
TrueType fonts.
If a customer application uses TrueType fonts, or bitĆmapped fonts, other than
those listed above, they must be added to the Windows configuration. If a font
file, needed by an application, is missing, then an error is generated and WinĆ
dows substitutes the closest" font it can find. This can lead to some interesting
results when the variableĆpitch system font is substituted for a fixedĆpitch font
(like Courier New).
Applications
Windows applications include the main executable program (with the .EXE exĆ
tension), the device driver files (with the .DLL extension), and other files that
are required for the main program to execute.

Often, you will find that an application's executable file is much smaller than the
functionality of the program would indicate. For example, the Microsoft PowerĆ
Point V4.0 main program is only 97K. Much of the functionality is implemented
in DLLs (PowerPoint includes one that is over
3 MB
). Therefore, it is important
that you get the full picture when sizing an application for the PEN*KEY 6000
Series Computer, by including allowances for any DLLs and other files needed by
the main program. It is also significant to note that certain development enviĆ
ronments require a huge library of routines to create an application that does
anything
. Power Builder, a prototyping tool, is one such program. The overhead
for creating a simple screen is around 3 MB.
