Show information about axes.
<p>
<li> `<font color="#82140F"><code>show color</code></font>'
Show the current pen color used for lines and text. This is not to be
confused with image color, which is independent.
<p>
<li> `<font color="#82140F"><code>show colornames</code></font>'
Show all colors known by name, as defined by `<font color="#82140F"><code>read colornames</code></font>'
command and also the builtin colors defined automatically
(e.g. `<font color="#82140F"><code>white</code></font>', `<font color="#82140F"><code>black</code></font>', `<font color="#82140F"><code>red</code></font>', etc),
(see <a href="Read.html#ReadColornames">Read Colornames</a>).
<p>
<li> `<font color="#82140F"><code>show columns</code></font>'
Show x, y, z, u, v column data.
<p>
<li> `<font color="#82140F"><code>show columns statistics</code></font>'
Show means, std devs, etc for columns.
<p>
<li> `<font color="#82140F"><code>show flags</code></font>'
Show values of all flags. (Developers only.)
<p>
<li> `<font color="#82140F"><code>show grid</code></font>'
Show an indication of the grid data (used for contouring).
<p>

region.
<p>
<li> `<font color="#82140F"><code>show image</code></font>'

it freely.
<p>

Show values of all synonyms, whether built-in or user-defined.
<p>
<li> `<font color="#82140F"><code>show stopwatch</code></font>'
Show elapsed time since first call to this command in the given Gri program.
<p>
<li> `<font color="#82140F"><code>show time</code></font>'
Show the current time.
<p>
<li> `<font color="#82140F"><code>show traceback</code></font>'
Show traceback (i.e., the tree of commands being done at this instant).
<p>
<li> `<font color="#82140F"><code>show variables</code></font>'

<p>
<li> `<font color="#82140F"><code>show {rpn ...}</code></font>'
Show result of computing indicated expression.
<p>
<li> `<font color="#82140F"><code>show "some text"</code></font>'
Print the indicated string. You may use a double-slash to prevent Gri
from substituting synonym values; thus it is common to do e.g.
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
\var = "Temperature"
show "Plotting \\var = 'var'"
</font></PRE>
</TD>
</TR>
</TABLE>
<p>
which will produce the output line
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
Plotting \\var = 'Temperature'
</font></PRE>
</TD>
</TR>
</TABLE>
<p>
<li> `<font color="#82140F"><code>show "time=" .time. "; depth=" .depth.</code></font>'
Print strings and values as indicated. If the last item is ellipses
(three dots with no spaces between them), then no newline is printed;
this makes the next `<font color="#82140F"><code>show</code></font>' statement print on the same line.
<p>
To get a newline in a printed string, use the three-character glyph
`<font color="#82140F"><code>\<<</code></font>', and to get a horizontal tab, use `<font color="#82140F"><code>\>></code></font>', as in the
examples below
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
\a = "HI"
show "\\a=\a"
system echo -e "a\\nb"
show "first line\<<second line"
show "first line\<<\>>(tabbed) second line"
show "first line\<<\>>(tabbed) second line"
</font></PRE>
</TD>
</TR>
</TABLE>

</ul>
