Comments are not evaluated texts. PPL supports both line comments and block comments.
Line comments begin with two slashes // and end with a new line.
Example::
os> source=accounts | top gender // finds most common gender of all the accounts
fetched rows / total rows = 2/2
+----------+
| gender |
|----------|
| M |
| F |
+----------+
Block comments begin with a slash followed by an asterisk \* and end with an asterisk followed by a slash */.
Example::
os> source=accounts | dedup 2 gender /* dedup the document with gender field keep 2 duplication */ | fields account_number, gender
fetched rows / total rows = 3/3
+------------------+----------+
| account_number | gender |
|------------------+----------|
| 1 | M |
| 6 | M |
| 13 | F |
