Set the Attributes of CONSTs (LAYOUT)

These are the items which can be set for CONST GQEs (LAYOUT):
/bo$*$rder=int_expr
0 - Do not draw a box around the workstation viewport. 1 - Draw a box around the workstation viewport.
/co$*$lour=int_expr
Frame colour, see the table in section 15.3.69.
/fo$*$nt=int_expr
Font number big tic mark numbers.
/grid_co$*$lour=int_expr
The grid is disabled, if the colour is set to 0.
/grid_ty$*$pe=int_expr
Line type of the grid, see the table in section 15.3.69.
/grid_wi$*$dth=float_expr
Line width of the grid.
/he$*$ight=int_expr
The height of the big tic mark numbers [pixel].
/ma$*$p_mode=int_expr
Map_mode = 1: 'Elastic paper' mode: Text heights, tic lengths and the distance between the axes and the big tic mark numbers change their size, if the viewport or the workstation viewport changes.

Map_mode = 2 (default): The above mentioned quantities are not scaled and axis descriptions (TEXTS that are outside the axes and have their fram set to NDC) keep their distance to the axis. In general users expect this mode. After they have choosen TEXT heights, etc. they don't want to see them change just because the plot becomes bigger or smaller.

/pl$*$ot_box=int_expr
Selects the way how the coordinate frame is displayed.
0 - Draw x- and y-axis. 1 - Draw axes as a box. 2 - Draw the upper right corner of the box. 3 - Draw box, leave right side open. 4 - Draw box, leave left side open. 5 - Both sides open.
/pr$*$ec=int_expr
The character size [points] for which the font was calculated. It is recommended to set it to 0.
/ty$*$pe=int_expr
Line type of the axes, see the table in section 15.3.69.
/wi$*$dth=float_expr
Line width of the axes, available in DEC_SPECTRA.
/x_o$*$ff=float_expr
/y_o$*$ff=float_expr
X-offset/y-offset of the major tic mark numbers at the y-axis/x-axis. The tic mark numbers are suppressed, if abs(offsets) > 2.
/x_maj_t$*$ic_size=float_expr
/y_maj_t$*$ic_size=float_expr
Size of the big tic marks (0 to 1). If the size is negative, the marks are plotted outside the frame.
/x_tic_s$*$ize=float_expr
/y_tic_s$*$ize=float_expr
Size of the tic marks (0 to 1). If the size is negative, the marks are plotted outside the frame.

e.g.:
SPECTRA> set layout /col=4 ]
Sets the frame colour to blue.
