Pause is useful in conjunction with load files. The command pause
displays any text associated with the command and then waits the
specified amount of time. This allows one to build a load file
and control the amount of time a finished graph is displayed. The
first argument is an expression that can be -1, 0, or a positive
integer. Choosing -1 will wait until a carriage return is hit. Zero (0)
won't pause at all, and a positive integer (such as 1 or 15) will
wait the specified number of seconds.
Note: Since pause is not part of the plot it may interact with
different device drivers differently (depending upon how text and
graphics are mixed).
Examples:
pause -1 ! Wait until a carriage return is hit
pause 3 ! Wait three seconds
pause -1 "Hit return to continue"
pause 10 "Isn't this pretty? It's a cubic-spline."
Syntax:
pause <expression> {"string"}
Note the string is optional, and if present must be enclosed in quotes.
