Basic Examples  (1)Summary of the most common use cases

Listable function threads over its list argument:

In[1]:=1
✖
https://wolfram.com/xid/0h2j9a370i-h38w0c
Out[1]=1

Clear the Listable attribute:

In[2]:=2
✖
https://wolfram.com/xid/0h2j9a370i-ejrrjo

Without the Listable attribute, the function applies to the entire argument only:

In[3]:=3
✖
https://wolfram.com/xid/0h2j9a370i-fpi5h
Out[3]=3

Scope  (1)Survey of the scope of standard use cases

Set a number of attributes for the symbol f:

In[1]:=1
✖
https://wolfram.com/xid/0h2j9a370i-e66pgr

Clear a particular attribute; the remaining ones are retained:

In[2]:=2
✖
https://wolfram.com/xid/0h2j9a370i-hfzjg0
In[3]:=3
✖
https://wolfram.com/xid/0h2j9a370i-edw09
Out[3]=3

Clear several attributes:

In[4]:=4
✖
https://wolfram.com/xid/0h2j9a370i-d1wc2x

Properties & Relations  (3)Properties of the function, and connections to other functions

ClearAttributes is equivalent to this assignment to the attributes:

In[1]:=1
✖
https://wolfram.com/xid/0h2j9a370i-si5wo
Out[1]=1

Unprotecting a symbol is equivalent to clearing the Protected attribute:

In[1]:=1
✖
https://wolfram.com/xid/0h2j9a370i-kr2p40
In[2]:=2
✖
https://wolfram.com/xid/0h2j9a370i-kilwlm
In[3]:=3
✖
https://wolfram.com/xid/0h2j9a370i-mhpvyv
Out[3]=3

After setting the attribute Locked, no more changes to the attributes can be made:

In[1]:=1
✖
https://wolfram.com/xid/0h2j9a370i-ir23xj
In[2]:=2
