# Getting Help for Functions

Updated: Aug 27, 2020

There are many different functions in Stata that you can use to generate new variables or perform calculations. For example, the **cond()** function which we cover in __this post__, or the **sqrt()** function which you can use to instantly calculate the square root of all the observations in a variable. There are many different functions in Stata that all have their own syntax. When you are trying to use a function, but you are unsure of the syntax, you can look it up using the **help** command. When you search using this command you must make sure to specify the brackets () at the end of the function name. This allows Stata to determine that you are looking for a function so it can find the correct help page.

This command will pull up the following help file for the function **cond()**:

Or this command for information on the **sqrt()** function:
