snp_export_data

	status.i4.v = snp_export_data(data_specs.g.v, user_dialog.i4.v
    				     [,top_row.i4.v] [,left_column.i4.v)

	This routine requests snapshot data to be exported from a snapshot
	plot process.  The specified snapshot plot process will mail an ASCII
	file containing the plot data or send the file to the requested user's.
	scratch file area.

	data_specs	default plot request values  (A value of NULL can be
			passed if this argument is not needed.  This argument
			must be specified if "user_dialog" is FALSE.)
			(structure of type snp_mail_t)
			(definition is in 'snpplt')
	user_dialog	(TRUE -> a user dialog box is presented allowing
				 input/modification of the plot request values,
			FALSE -> use values specified by "data_specs")
       [top_row]       if user_dialog is TRUE, this argument is top row of
			user dialog box (use WMNGR_CENTER for centering
                       or WINDOW_xxx_COORD macros in macro for special
                       positioning)
       [left_column]   if user_dialog is TRUE, this argument is left column
			of user dialog box (use WMNGR_CENTER for centering
                       or WINDOW_xxx_COORD macros in macro for special
                       positioning)

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid plot request values passed or entered
	CBS_WINDOW_TOO_BIG	dialog window won't fit on screen
	CBS_MEMFAIL		dynamic memory allocation failure
	CBS_ABORT		user aborted dialog
	ACNET_xxx		error translating destination node or
				send mail message

	This function requires the following include files:

	cnsparam_h, cbslib_h, snpplt_h, acnet_errors_h
