You’re defining a command named \hello which has to be followed by the
string "-world_2".
You can use the following example as test.
%%%% begin example
\starttext
\def\hello-1{Hello \letterhash 1}
\def\hello-2{Hello \letterhash 2}
\hello-1
\hello-2
\stoptext
%%%% end example
Here I create a command named \hello which has to be followed by “-1"
and "-2".
When you run TeX on this example you get the following error message:
%%%% begin error message
tex error > tex error on line 7 in file /Users/wolf/TeX/test/test.tex: !
Use of \hello doesn't match its definition
l.7 \hello-1
%%%% end error message
