    `show ...'
- Show some information by printing it to standard output. ``show all`' Show lots of information about plot. ``show axes`' Show information about axes. ``show color`' Show the current pen color used for lines and text. This is not to be confused with image color, which is independent. ``show colornames`' Show all colors known by name, as defined by ``read colornames`' command and also the builtin colors defined automatically (e.g. ``white`', ``black`', ``red`', etc), (see Read Colornames). ``show columns`' Show x, y, z, u, v column data. ``show columns statistics`' Show means, std devs, etc for columns. ``show flags`' Show values of all flags. (Developers only.) ``show grid`' Show an indication of the grid data (used for contouring). ``show grid mask`' Show 1 if grid data are valid or 0 if contours will not extend into this region. ``show image`' Show information about image, such as a histogram of values, and, if the image is small enough, the actual data. ``show license`' Show the license for Gri, which outlines how users are allowed to share it freely. ``show misc`' Show miscellaneous information about the plot, the data, etc. ``show next line`' Show next line of data-file. ``show synonyms`' Show values of all synonyms, whether built-in or user-defined. ``show stopwatch`' Show elapsed time since first call to this command in the given Gri program. ``show time`' Show the current time. ``show traceback`' Show traceback (i.e., the tree of commands being done at this instant). ``show variables`' Show values of all variables, whether built-in or user-defined. ``show .value.`' Show value of indicated variable. ``show {rpn ...}`' Show result of computing indicated expression. ``show "some text"`' 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.
      \var = "Temperature"
      show "Plotting \\var = 'var'"
  which will produce the output line
      Plotting \\var = 'Temperature'
- ``show "time=" .time. "; depth=" .depth.`' 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 ``show`' statement print on the same line. To get a newline in a printed string, use the three-character glyph ``\<<`', and to get a horizontal tab, use ``\>>`', as in the examples below
      \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"
