variables

The program KUPLOT recognises various variables. The contents of a variable can be displayed using the 'eval' command. Some variables are READONLY (RO) and can not be changed.

Free variables :
----------------

"i[<n>]"           : integer variables (currently 0 <= <n> <= 59)
"r[<n>]"           : real variables    (currently 0 <= <n> <= 59)
KUPLOT specific variables :
---------------------------
"x[<ik>,<ip>]"     : x value of point <ip> in loaded data set <ik>.
"y[<ik>,<ip>]"     : y value of point <ip> in loaded data set <ik>.
"dx[<ik>,<ip>]"    : value of sigma x of <ip> in loaded data set <ik>.
"dy[<ik>,<ip>]"    : value of sigma y of <ip> in loaded data set <ik>.
"z[<ik>,<ix>,<iy>" : z value of point <ix>,<iy> of loaded data set <ik>.
"nx[<ik>]"         : # points in x-direction of data set <ik>. (RO)
"ny[<ik>]"         : # points in y-direction of data set <ik>. (RO)
"ni[<ik>]"         : data set <ik> is 2D (=0) or 3D (=1).      (RO)
"np[<ik>]"         : # points of 2D data set <ik>.             (RO)
"xmin[<ik>]"       : minimum x-value of data set <ik>          (RO)
"xmax[<ik>]"       : maximum x-value of data set <ik>          (RO)
"ymin[<ik>]"       : minimum y-value of data set <ik>          (RO)
"ymax[<ik>]"       : maximum y-value of data set <ik>          (RO)
"zmin[<ik>]"       : minimum z-value of data set <ik>          (RO)
"zmax[<ik>]"       : maximum z-value of data set <ik>          (RO)
"n[1]"             : number of loaded data sets                (RO)
"n[2]"             : maximum number of data sets               (RO)
"cmap[<ic>,3]"     : colour map entry RGB for colour <ic>
"cmax[1]"          : maximum number of bitmap colours          (RO)
"cmax[2]"          : bitmap colour modus :
                     -2 : Postscript colour + new colourmap X11
                     -1 : Postscript gray  + new colourmap X11
                      1 : Postscript gray  + old colourmap X11
                      2 : Postscript colour + old colourmap X11
Variables containing command results :
--------------------------------------
"res[<n>]"          : Result of several calculations that return more
                      than one value.  res[0] contains the number of
                      values returned, res[1] to res[res[0]] contain the
                      actual values.  The values of "res" change everytime,
                      a command is applied that returns more than one
                      value. The old values are lost !
