SQLPlus environment settings before running a script

Hello,

We are going to run scripts that include a lot of insert and update statements on sqlplus 10g and we want to avoid sqlplus stopping for special characters in text fields.

For the "&" character we will use the SET DEFINE OFF setting so that sqlplus does not prompt for a value.

Documentation states that SET SCAN OFF is obsolete and SET DEFINE OFF is the alternative command

Are there any other settings or ideas that we can use so that sqlplus doesn't complain about special characters in text fields?

Thank you for your help.
