[texhax] question regarding baselines

[Steven E. Ganz]

I am looking for a way to have an array such that adjacent text to the
left is vertically aligned with the top row and adjacent text to the
right is vertically aligned with the bottom row.  That is exactly what
one needs for typesetting code, using macros for each syntactic form, 
but it seems to violate fundamental constraints of tex.  I am aware of
alltt and lstlisting, but would prefer to generate the code using 
macros.

Is there any way get this effect?
