ISSUE:       3303
TITLE:       Incorrect execution of volatile SQL statements inside EXECUTE STATEMENT
DESCRIPTION:
JIRA:        CORE-2920
FBTEST:      bugs.core_2920
NOTES:
    [25.11.2023] pzotov
    Writing code requires more care since 6.0.0.150: ISQL does not allow specifying duplicate delimiters without any statements between them (two semicolon, two carets etc).
