parameter substitution in SQL*PLUS

I would like to execute an update statement as follows:

update table1 set field1 = 'long & lean' where record_id = nn;

where the literal string 'long & lean' contains the ampersand character (&) as a literal character. While there is nothing in SQL to dissallow this, the SQL*PLUS window environment keys on this character as a parameter substitution character and prompts me to enter a value.

If I have this update statement in a script in a file, how can I escape the "&" character when submitting the script to the database thru SQL*PLUS? Thanks in advance for anyone's help on this.
