RegisterFonts% function

 Action
 Registers the font-header information from a specified .FON file and returns
 the number of fonts registered.

 Syntax
  RegisterFonts% ( filename$)


 Remarks
 The  RegisterFonts% procedure registers the font-header information from the
 .FON file specified in  filename$. The font-header information is stored in
 the registered-fonts array. This array corresponds to the loaded-fonts array
 which contains the character-bit maps of the fonts stored in the .FON file.
 Because an .FON file may hold one or more fonts,  RegisterFonts% returns the
 number of fonts registered by the function.

 This procedure will register any number of fonts up to the maximum set with
 the  SetMaxFonts procedure or to the limit of available memory.


 Note
 When using the  RegisterFonts% procedure, be sure you have access to the
 .FON file on disk so that it can find the filename of the currently selected
 font.

 For more information on loading the fonts, see the  LoadFont% procedure.
