			Jackfont is a monochrome-only utility program designed to edit fonts 
			used by any program which uses GDOS, or GDOS fonts (at the moment 
			only a few like Easydraw, Degas Elite and Fleet Street Publisher 
			allow multiple GDOS fonts). As such, it is a God-send as until now 
			there has been no good font editor available either on the Atari ST 
			or the IBM PC.
			 
			Jackfont has 
			three windows that it uses for font editing. The main one is a large 
			grid display (from 5x3 to 72x80) typical of font editors and the 
			second large one (the Select Box) contains a full 256 character 
			display from which the character to edit is selected. There is also 
			a small 'actual size' window in which nine variations (bold, 
			underlined etc.) of the character can be displayed. The process of 
			editing a character is to select the character in the Select Box, 
			and then use the mouse in the main editing grid to invert pixels.
			
			Rolls, shifts, mirrors and flips can also be done and three fonts 
			are supplied for experimentation. When the character is to your 
			satisfaction, you select another to edit — the edited character is 
			copied back automatically. When the whole font is finished, you can 
			save it back to disk (choosing another filename if you desire).
			
			Dialogs are available to allow setting of all the various variables 
			associated with a GEM font, including the point size, the Top, 
			Ascent, Descent, Bottom and Half values, the file format (Intel or 
			Motorola), proportional, skewing and more. A very useful dialog is 
			an automatic re-sizing facility, which stretches the current font to 
			make a complete range of sizes easily. Also available is a test 
			screen where the current character is inserted in a sentence and 
			displayed in several type styles. It is such a pity that this is not 
			complimented by a complete display of all the font's characters 
			on-screen at once, as this would be invaluable.
			
			The manual starts with a most educating overview of fonts and is a 
			credit to Vogler. Only a few bad points (no pun intended) — the 
			manual describes the 'ID Number' as 'purpose unknown, is used 
			internally by GEM. It is best to skip this item as GEM doesn't 
			appear to care what its value is.' As a programmer who has used GDOS 
			(FaSTcom) I happen to know that this is how a programmer actually 
			selects a particular font. In a general CAD or DTP program this is 
			not apparent, but when you want only one font, (e.g. viewdata) you 
			need to know the fond ID to select it. Different sizes of an ID are 
			selected with point sizes.
			
			JackFont has some awkward techniques of item selection, and one is 
			acknowledged in the manual. Because the selector and editor are in 
			separate windows, you must first click in the window before you can 
			work in it. In the case of the edit window, if you start clicking 
			too soon, the first click is mis-understood, and you must click on 
			another pixel before it will start editing. The manual tries to 
			excuse this, but it is really bad programming, and should be fixed. 
			Also the Select Box window should not 'top' when clicked in, but 
			should just work out where you clicked and set up the appropriate 
			character for editing. Topping the window continuously soon wears 
			you out, and there is nothing else to be done in the Select Box 
			anyway. A key to step to the next / previous character would be 
			useful here. Also needed is auto-update of the small 'actual size' 
			screen.
			
			If you have one of the programs mentioned at the beginning of the 
			review, or are interested in GDOS fonts, then this program has 
			nothing to touch it on the market at the moment. I shall be using it 
			often, though I look forward to a new version with the irritations 
			removed.
