Clearing macros

Question

The following command removes all variables, scalars and programs that I add:

clear all 

However, global and local macros stick around.

I would like to know how to clear these out:

• interactively from the command line and/or
• as an opening line in my do files

Answer 1

You can drop all macros with:

macro drop _all 

This is documented in help macro and the corresponding manual entry.

Answer 2

The command below also removes some of my other global macros, which I do not want to remove:

macro drop _all

I prefer the following command, which tells you all the macros you have defined:

macro list _all

For example, x1, x2, x3, y1, y2, y3, z1, z2 and so on.

If you then just want to drop only macros y and z (but not x), then you can use this command:

capture macro drop y1 y2 y3 z1 z2

or

capture macro drop y* z*
