VMS Instructions

All the QDP/PLT software can be used by adding a few lines to your LOGIN.COM file. First, you must define the XANADU logical name (to create a virtual disk). In brief, if QDP is in the directory called DRB1:[XRAY.BIN], then the following line should be in your LOGIN.COM:

$ DEFINE/TRANS=(TERM,CONCEAL)   XANADU   DRB1:[XRAY.]

(The above line is very system dependent.) In this example, DRB1: is the physical device name. If you do not translate to the physical device name, but to a logical name (for example, USER:[XRAY.]) then you should omit the TERM option for the /TRANS switch. You will need to define the the following logical names:

$ DEFINE   GRAPHICS   XANADU:[PLOT.PGPLOT]
$ DEFINE   GRPSHR     GRAPHICS:GRPSHR.EXE
$ DEFINE   PLT$FONT   GRAPHICS:GRFONT.DAT
$ DEFINE   UFNYSHR    XANADU:[LIB]UFNYSHR.EXE

GRAPHICS should point to the top level PGPLOT directory. In the above example, this was assumed to be XANADU:[PLOT.PGPLOT] and should be changed appropriately if PGPLOT lies in another location. GRPSHR and PLT$FONT should not need to be changed. You will also need to setup symbols pointing to both QDP and COD with

$ QDP      :==$ XANADU:[BIN]QDP
$ COD      :==$ XANADU:[BIN]COD
