Hi,

The manual says:
=============================================================
ifdef variable-name
The ifdef form takes the name of a variable as its argument, not a
reference to a variable. The value of that variable has a non-empty value, the
text-if-true is effective; otherwise, the text-if-false, if any, is effective.
Variables that have never been defined have an empty value. The text
variable-name is expanded, so it could be a variable or function that expands
to the name of a variable.
================================================================
The second sentence of the first paragraph has a grammar error, it looks like
it should read "If the value of that variable..."
Also, "The value has a ... value" seems awkward.
