Correct path and name of test database file and run this script:

shell del C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp 2>nul;

set list on;
set echo on;

create database 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey'
;
drop database;
commit;

create database 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey' --
;
commit;

connect 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey' --
;
commit;

connect 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey'
;
drop database;
commit;

Output will contain:

connect 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey' --
;
Command error: connect 'localhost:C:\MIX\firebird\QA\fbt-repo\tmp\tmpfdb.tmp' user 'SYSDBA' password 'masterkey' --
