SYNOPSIS

DESCRIPTION

This is the routine that generates a copy of the current plot by closing the current device and opening another, calling the same routine as the PLOT command, and then closing the new device and opening up one like you started from.

This works best when the current device is an interactive device such as X11 or tek; as exiting and reinitializing usually does not effect an interactive device much; but for file oriented devices the output file is restarted (as the current version of M_plot is written).

So, one limitation here is that if you running a batch job that is making PostScript output and you call the plot_hcopy command to generate a bitmap file, for example, your current PostScript output file is going to be restarted.

Consider making M_plot support concurrent open devices, or a special exit that is "temporary" and lets you resume output. Actually, I think Bernie’s last version does that?

Note that if the -obj option is used, instead of calling the equivalent of PLOT a special object is called. This could be used by a sophisticated user, but is used to copy what shows on screen from ID, SHOWFONT, ... commands too.
