NAME zs - close filter, synchronous
SYNOPSIS zs
DESCRIPTION Like the zx, or close-
filter, command, the close-filter, synchronous, command tells the
filter process that the current plot is finished, but it also
causes C-PLOT to pause until the filter is
finished writing to your terminal.
The synchronization option is especially useful for filters
that write graphics commands to your terminal over the same
serial line as ordinary text, keeping the filter program's
graphics commands from getting garbled with text from the plot
program.
For example, zqzkds draws the plot, key and date
with quiet mode on and prevents the PLOT-> prompt
from being issued until the last graphics command has been sent
to the terminal. As with zx, a second
<return> will switch to text mode.
When running C-PLOT in the background, the
synchronization capability is disabled, and zs is
equivalent to zx.
(Filters from older versions of the C-PLOT
package don't support the synchronous close option and will cause
the plot program to hang when you enter zs. Typing
^C will make the plot program continue.)
For general information on graphics filters, see the
filters help file.
