In the foregoing paragraphs, I seem to have lept into the middle of complexity. Let me approach from a different starting point. Evidently, one or another member of this enterprise will be preparing a compiler, or compilers, for modifying existing programs that compile FORTAN [sic.], JOVIAL, ALGOL, LISP and IPL-V (or V-l, or V-ll). If there is more than one of any one of the foregoing, or of any one of others that I do not foresee, then it seems worthwhile to examine the projected efforts for compatibility. Moreover, to me, at least, it seems desireable to examine the projected efforts to see what their particular features are, and to see whether there is any point in defining a collection of desireable features and trying to get them all into one language and one system of compilers.
