APL is definitely an imperative language.

On the other hand, APL is not very good for writing programs
in the way that they would be written in, for example, C.
Imperative is not the same as procedural.  Assembly language,
for example, is certainly an imperative language, but not
really suited to procedural programming.

APL does have procedures, but they are not up to even the
level of procedural programming offered by Pascal.  It isn't
that it's impossible to do procedural programming in APL,
but the impedance mismatch makes it feel like swimming in
molasses.

Further explanation in my response to Ben Bacarisse in this
thread.
