We have started having fun with built-in functions (set of instructions) for strings (character arrays).

1. UPPER() — upper case
2. LOWER() — lower case
3. RTRIM() — trim spaces on the right
4. LTRIM() — trim spaces on the left
5. RIGHT() — part of a string starting on the right
6. LEFT() — part of a string starting on the left
7. SUBSTRING() — part of a string in the middle
8. LEN() — length of a string
9. REPLACE() — to replace part of a string
