error_query_setup

	init.i4.v = error_query_setup(error_row.i4.r, error_column.i4.r,
				      error_length.i4.r, write_log.i4.r,
				      log_file.i1a.r, author.i1a.r,
				      num_rows.i4.r)

	This routine returns the current error display setup from the most
	recent call to error_init(_c).  If any of the returned parameters
	are not needed, a value of NULL can be passed for that argument.

	error_row	returned TV window row location of message
	error_column	returned TV window column location of message
	error_length	returned maximum number of characters used for
			error messages
	write_log	returned error logging information
			(LOG_NONE -> no log entries written,
			 LOG_PROGRAM -> log entries in the program log,
			 LOG_CONSOLE -> log entries in the console log,
			 LOG_BOTH -> log entries in both logs)
	log_file	returned log file name (LOG_NAMLEN characters)
	author		returned author string (LOG_AUTLEN characters)
	num_rows	returned number of error display rows
			(If "num_rows" > 1, a scrolling error message
			 window is present.)

	This function returns status values as follows:

	TRUE			error_init(_c) has been called
	FALSE			error_init(_c) has not been called

	This function requires the following include files:

	cnsparam_h, cbslib_h
