Function: playback (grind) Displays input, output, and intermediate expressions, without recomputing them.
playback only displays the expressions bound to labels; any other output (such as text printed by
describe, or error messages) is not displayed. See also
playback quotes its arguments. The quote-quote operator
playback always returns
playback () (with no arguments) displays all input, output, and intermediate expressions generated so far. An output expression is displayed even if it was suppressed by the
$ terminator when it was originally computed.
playback (<n>) displays the most recent <n> expressions. Each input, output, and intermediate expression counts as one.
playback ([<m>, <n>]) displays input, output, and intermediate expressions with numbers from <m> through <n>, inclusive.
playback ([<m>]) is equivalent to
playback ([<m>, <m>]); this usually prints one pair of input and output expressions.
playback (input) displays all input expressions generated so far.
playback (slow) pauses between expressions and waits for the user to press
enter. This behavior is similar to
playback (slow) is useful in conjunction with
stringout when creating a secondary-storage file in order to pick out useful expressions.
playback (time) displays the computation time for each expression.
playback (grind) displays input expressions in the same format as the
grind function. Output expressions are not affected by the
grind option. See
Arguments may be combined, e.g.,
playback ([5, 10], grind, time, slow).
