Basic Examples (1)
Commands to define a simple package:
| In[1]:= |
The context for symbol creation has been changed to 
:
| In[2]:= |
| Out[2]= |  |
The context path for symbol lookup includes 
:
| In[3]:= |
| Out[3]= |  |
Here are the commands defining the function in the package:
| In[4]:= |
| In[5]:= |
Restore the context, but leave 
on the context path for symbol lookup:
| In[6]:= |
Since EndPackage leaves 
on the context path, the function defined is visible:
| In[8]:= |
| Out[8]= |  |
