4. Installing/Deleting Java

4.1 Installing the Library

• Send the library to the HP 48
• Put a copy of the library on the stack.
• You may now PURGE the variable containing the library.
• Enter the port number you wish to store the lib (0/1 on GX, 0/1/2 on SX)
• Press STO
• Warmstart with ON-C, or power-cycle
• Install a UFL library that supports FNT2
• Run STK and configure Java. Select "Java Active" or run JAVA

4.2 Deleting the Library

• Press the JAVA key or clear flag 64 to quit
• The library is still referenced in memory, so warmstart with ON-C
• Type :&: 908 then press ENTER ENTER
• Type DETACH PURGE
• The display should "flick" slightly - don't worry, it's normal.
• You can also purge the UFL if none of your other programs require it

4.3 Universal Font Library

In order to run Java, you will need need a copy of the Univeral Font Library (UFL) installed that supports FNT2. Java does not require FNT1 because it contains its own customized variable width smallfont.

Currently the only UFL libraries that support FNT2 are levels 2 and 3. As such, you will need to install either `ufl2.lib' or `ufl3.lib'. You must obtain the actual UFL package for these libraries as well as usage instructions, access routines, and the font maintenance library.

These should be available at the standard HP48 FTP sites, or at http://www.engr.uvic.ca/~aschoorl/ufl/
