Example 1: [[ 1 1 1 1 ][ 1 1 1 1 ][ 1 1 1 1 ]] 6 [[ 2 2 ][ 2 2 ]]
REPL
returns [[ 1 1 1 1 ][ 1 2 2 1 ][ 1 2 2 1 ]] .
Example 2: { A B C D E } 2 { F G } REPL returns { A F G D E } .
Example 3: ERASE PICT (0,0) # 5d # 5d BLANK NEG REPL replaces a portion of
PICT with a 5 x 5 graphics object, each of whose pixels is on (dark), and whose upper left corner
is positioned at (0,0) in PICT.

RES
Type: Command
Description: Resolution Command: Specifies the resolution of mathematical and statistical plots, where the
resolution is the interval between values of the independent variable used to generate the plot.
A real number n
interval
specifies the interval in user units. A binary integer #n
interval
specifies the
interval in pixels.
The resolution is stored as the fourth item in PPAR, with default value 0. The interpretation of
the default value is summarized in the following table.
Plot Type Default Interval
BAR 10 pixels (bar width = 10 pixel columns)
DIFFEQ unlimited: step size is not constrained
FUNCTION 2 pixels (plots a point in every other column of pixels)
CONIC 2 pixels (plots a point in every other column of pixels)
TRUTH 2 pixels (plots a point in every other column of pixels)
GRIDMAP RES does not apply
HISTOGRAM 10 pixels (bin width = 10 pixel columns)
PARAMETRIC [independent variable range in user units]/130
PARSURFACE RES does not apply
