Maps and Legends ST FONT LOADER Written by Alan Page WORKS WITH TOS IN ROM AND RAM This accessory loads either DEGAS fonts or XL/XE-type fonts (as on the Maps and Legends disk). It works with TOS in ROM or RAM, although with the original TOS in RAM you will have to rename the file to DESKn.acc where n is the appropriate number (1 to 6). It also works in either color or monochrome. INSTRUCTIONS When you select ST Font Loader from the menu bar, an alert box appears with the copryight notice and two buttons: [ OK ] and [ CANCEL ]. If you select [ CANCEL ], the alert disappears and the fonts remain unchanged. If you select [ OK ], the file selector appears and you can choose the font to install from the disk. If you select [ CANCEL ] on the file selector, no changes are made. RESTORING THE SYSTEM FONT If you manually type in the filename SYSTEM.FNT, the original system font will be restored. It isn't necessary to have an actual file named SYSTEM.FNT. Simply type it in the file selector and press return (or select [ OK ]). (You may also want to put a dummy, empty file named SYSTEM.FNT on the disk anyway, to remind you.) DEGAS FONTS AND XL FONTS ARE DETECTED AUTOMATICALLY When you have selected a font to load, the accessory checks the file size. If it is at least 2050 bytes long, then it assumes it is a DEGAS font. (It can be more that 2050 bytes to allow for padding caused by xmodem transfer) If the file is less than 1024 bytes long, then it can't be a font file and an alert box warns you of this. You also get alert boxes if there are disk errors. Page 28 Maps and Legends SUBDIRECTORIES ARE SUPPORTED You may want to put all of your fonts in a subdirectory, or in drive number two, or both. In fact, if you simply copy FONT.ACC out of this folder and into a root directory of your boot disk, you can use the fonts on this disk the following way: 1. When the file selector box appears, click on the top line or press the up-arrow. Then press escape to clear the line. 2. Type: A:\FONTACC\*.FNT - or, if in drive B - B:\FONTACC\*.FNT 3. Click on the grey horizontal bar to the right of the close button to update the file selector. ST Font Loader is smart enough to know where you keep your fonts, but you have to tell it where they are once. ERROR CHECKING, OR... IS IT A FONT? There is no checking to see if the font data is valid because there is no simple way to distinguish font files from other files. You can type in or select any filename, and as long as it is at least 1024 bytes long, the accessory accepts it. If it is not a font file, however, it will look like garbage. THE SYSTEM FONT IS ALWAYS AROUND There is an alert to tell you a new font has been installed. And when a new font is installed, characters will still appear in the old font until the system redraws them. Text in the VT-52 desk accessory, file listings from the desktop and text in FLASH's terminal screen remain unaffected because TOS gets those characters from the original system font. Page 29
