Scheduler Chain script generated by Toad is missing some quotes. The DDL script is invalid. (4295908)

Scheduler Chain script generated by Toad is missing some quotes. The DDL script is wrong, invalid or incomplete.

The word SUCCEEDED has 2 single quotes on left side and 3 single quotes on right side, but the script created by TOAD has 1 single quote on left side and 2 single quotes on right side. ('SUCCEEDED'' instead of ''SUCCEEDED''')

The script below is a sample (valid or correct) script.  The issue will show once you create this object in the database and view it in Schema Browser | Sched. Chains | Script tab.
