WHO  WHO Describe Currently Defined Variables


Usage
 
 Reports information on either all variables in the current context
 or on a specified set of variables.  For each variable, the who
 function indicates the size and type of the variable as well as 
 if it is a global or persistent.  There are two formats for the 
 function call.  The first is the explicit form, in which a list
 of variables are provided:
 
   who a1 a2 ...
 
 In the second form
 
   who
 
 the who function lists all variables defined in the current 
 context (as well as global and persistent variables). Note that
 there are two alternate forms for calling the who function:
 
   who 'a1' 'a2' ...
 
 and
 
   who('a1','a2',...)
