Append string to a macro

How to append a string to a macro in spec file? For example I have
defined a macro:
%define release 234
I want to append a string, for example "beta", to this macro somewhere
below this definition. I don't want to do it like this:
%define release 234beta
because I'd like to make a patch that I'd be able to apply to different
versions of spec file.

I tried:
%define release %{release}beta
%define release %(echo %{release}beta)
%{expand: %%define release %{release}beta}
%{expand: %%define release %%{release}beta}
and I got an infinite recursion every time.

Of course you did.

Use two macros:

%define baserelease 234
%define release ${baserelease}beta
