#Xlist command in stata code

You may occasionally see code that excludes the = in defining a macro (e.g. You can use display to print the content of macros to the output to preview them. Local pricelab = 'Price (in dollars) at Time Point' Label variable price2 'Price (in dollars) at Time Point 2' Label variable price1 'Price (in dollars) at Time Point 1' If your macro contains text that should be quoted, you still need to quote it when accessing. Important: Local macros are deleted as soon as code finishes executing! That means that you must use them in a do-file, and you must run all lines which create and access the macro at the same time, by highlighting them all. Stata immediately replaces `vars’ with var1 var2 var3 var4 var5, then executes Whenever it is referred to, wrapped in a backtick (to the left of the 1 key at the top-left of the keyboard) and a single quote, Stata replaces it with the original text. The first command, local, defines what is known as a “local macro” 14. Instead, we can store the list of variables (strictly speaking, the string which contains the list of variables) in a shorter key string, and refer to that instead! You could copy and paste a lot, but even that takes a lot of effort.

This can get extremely tedious as the number of variables and commands increases. Label values var1 var2 var3 var4 var5 mylab Imagine the following scenario: You have a collection of 5 variables that you want to perform several different operations on. While variables stored as strings aren’t of much use to us, strings stored as other strings can be quite useful.
