status.i4.v = ftp_start(plot_info.s.r [,erase_it.i4.v]

	This routine starts up a fast time plot.

	plot_info	plot information structure depending on the
			value of "version"
			(1 -> structure of type FTP_INFO,
			 2 -> structure of type FTP_INFO_2)
	[erase_it]	plot erase flag
			(TRUE -> erase present plot (default),
			 FALSE -> start plot without erasing old one)
	[version]	plot interface version
			(1 -> original plot interface,
			 2 -> current plot interface)
			(default is 1) 

	This function returns ACNET status values as follows:

	OK			success
	CBS_WINDOW_TOO_BIG	plot window won't fit on screen

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, cbslib_h, acnet_errors_h
