PLS-00103: Encountered the symbol "CREATE"

I wrote a SQL script as below, while executing it, encountered 'PLS-00103: Encountered the symbol "CREATE"' error.

=============

The problem is forgetting to add '/' for the first procedure. When we encounter this kind of issue, usually, we miss adding something or the variable is reserved one etc.
