Short: Translates TeX's DVI-Code into dvi code for HP Laserjet+

/**********************************************************************
 ****************************  Intro  *********************************

 * code of either the
 *
 *     -   HP-LASERJET+ and compatibles (PCL), or the
 *     -   IBM 3812 pageprinter
 *
 * depending on the preprocessor switches specified before compilation.
 * The program is written to run on a PC XT/AT/PS2 under MS-DOS. It can
 * be compiled nicely with MSC Rel. 3.0-5.1 with option -AL (large memory
 * model).  Take care that in the CONFIG.SYS file the FILES parameter
 * is set to 20; otherwise reduce MAXOPEN.  640K are recommended.
 * I use link option /stack:9000 to increase runtime stack.
 * It also works without modifications under Unix System V.
