SUBROUTINE WHEREVT

         

 WHEREVT returns information on the  terminal plotting parameters. If nv <= 0 then terminal graphics have not been initialized. A routine  FIXVT0 (with same arguments) may be used to set these variables to  absolute values without error checking.

CALL WHEREVT (x,y,z,a,rx,ry,iv,ns,it,iw,ic)

x,y   (R): (returned) current origin
z     (R): (returned) current zoom scale factor
a     (R): (returned) current plotting angle
rx,ry (R): (returned) current pixel resolution
iv    (I): (returned) terminal code
              (if nv <= 0 terminal is not initialized)
ms    (I): (returned) internal terminal-type code
           = 1 VT100 with Selanar GR100
           = 2 VT125 
           = 3 VT240 
           = 4 VT220 with Selanar GR220
           = 5 Tektronix 4010
           = 6 Tektronix 4109
           = 7 Graphon GO-235
it    (I): (returned) current line type 
iw    (I): (returned) current line width
ic    (I): (returned) current line color
