Using MaxL in batch script to get Essbase database size before proceeding

Question

I have a batch script which dynamically generates some MaxL before passing it to ESSMSH. I would like to insert a command at the beginning of the MaxL script, to get and assess the size of the database before proceeding. If the database is empty I would like the script to quit. This is to prevent the script from exporting data and overwriting the previous export file if the database is empty.
The generated MaxL (modified) is currently as follows. What logic can I add to the MaxL script, to assess the database size and go to the "errorhandler" label if it is empty? Is this even possible?
login %USER% identified by %PASS% on %SERVER%;
iferror "errorhandler";
/* log file */
spool stdout on to '<directory>.log';
iferror "errorhandler";
/* error file */
spool stderr on to '<directory>.err';
iferror "errorhandler";
/* export data */
set timestamp on;
execute calculation %APP%.%DB%.C_Export;
iferror "errorhandler";
/* reset database */
alter database %APP%.%DB% reset data;
iferror "errorhandler";
/* import data */
import database %APP%.%DB% data from server data_file "<filename>.txt" on error abort;
iferror "errorhandler";
/* calculate database */
execute calculation default on %APP%.%DB%;
iferror "errorhandler";
/* error handler */
spool off;
define label "errorhandler";
logout;
exit;

Hi Stuart,
Yes I was aware of display database "app"."db"; however this will output a table rather than a specific value. And what logic can I then add to the MaxL script to assess the specific value of "Db Status" and go to the "errorhandler" label if it is empty?
It would seem this needs to be done via a VBScript, to loop through the file rows to find the value before proceeding accordingly. But I was hoping there might be a way to do this within MaxL.
