In the process of a project, I realized it would be helpful if I could do as follows. Say I have a list of different commands (simplified):
\newcommand{\AA}{...}
\newcommand{\AB}{...}
\newcommand{\AC}{...}
...
\newcommand{\AZ}{...}
Now I want a command that can call one of these commands (based on input):
\newcommand{\caller}[1]{\A#1}
The example above won't work, but how would I go accomplishing something that has such a functionality?
