I have a single *.tex file that I have setup, here's a simple minimal example:

\define\macroA{This outputs some stuff.}

\define\macroB{\input knuth }

\define\macroC{This outputs other stuff.}

\define\macroD{This outputs other stuff.}

\define\macroE{This outputs other stuff.}

\define[2]\macroF{This is text #1 and #2.}

\define\macroG{This outputs other stuff.}

\define\macroH{This outputs other stuff.}

\starttext

\macroA
%\macroB
%\macroC
%\macroD
%\macroE

%%% some more code

\macroF{a}{b}
\macroG
\macroH

\stoptext

Normally, I will compile it as above, so only two of the macros actually appear. But sometimes, for testing purposes, I want to make sure my code is functioning good, so I will go an un-comment all of the macros, and then compile, and it basically does a test, making sure all of the macros in my code function perfectly. When testing, it looks like this:

\starttext

\macroA
\macroB
\macroC
\macroD
\macroE

%%% some more code

\macroF{a}{b}
\macroG
\macroH

\stoptext


Because the actual file is quite large, commenting and un-commenting the lines takes a long time, and can lead to mistakes. Is there any simpler way to easily switch between the two versions?
