how can I test for the existence of a financial time series object?

This seems like it would be really easy, but I can't figure it out.
Basically, i want to see if time series A exists, and if it does, I want to make C=merge(A,B). If A doesn't exist, then I just want C=B.
Thanks for any help.
Best, Mike

doc exist
if exist('A')
C=merge(A,B);
else
C=B
end
I don't have Finan Toolbox so can't test; I presume exist will return 8 as a class if it does exist. Of course, any nonzero value means there is an A of some sort extant as the logic above is written it doesn't care which type of object it may be.

isa and exist will be your friends.
if exist('A','var') && isa(A,'timeseries')
C = merge(A,B)
else
C = B;
end
