Examples/Module: dplvar (example 2)

Example
The first line's statements set the variables initially as: ' to, ' to  , and ' to  ; then the following variables also have a default set: '  to  , ' to  , and ' to.

The last four lines display the value of each corresponding variable in a bulleted list format.


 * a:
 * b:
 * c:
 * d:

Result

 * a:
 * b:
 * c:
 * d:

Notes:
 * Variable "c" was set to "cccc" because although it was already set, its note is equivalent to an empty value.
 * Variable "d" was set to "dddd" because it was not already set.
