All scripts should contain minimal remarks to document the writer, the date, and the purpose of the report.
Remarks are called "comments" in other languages.
Remarks are allowable anywhere in the script except for within the SELECT statement.
Remarks start with REM in each line.
In the SELECT statement, normal comments may be used: /* comment */ or two dashes at the end of a single line.
Here is the above script with some remarks, indicated by REM:
