The satellite functions for apply are the following:app2[f ;x;p] : machine languageThe function app2 is the apply operator (see apply) in thecase when f is atomic.app2[f;x;p] = select[f; [c~R;caar[x]]; [C~R;cdar[x]l;[CONS;cons[car[x]~cadr[x]]];[~~~~jx];search~A[ [ j];[eq[car[ jl;~UB~l~eq[car[jl;~~~~l11;A[[ jl;[eq[car[ j1;SUBRI + app3[cadr6jl;xl;T -+See the function select.A[[ jl;app~y[car[sassoc[f;p;errorIl~x;plapp3 [ f; x] : machine languageIn the case when - app2 (see above) in the apply functionfinds an atomic function specified by a machine-language subroutine,- app3 applies that subroutine to the list x of arguments.I I I
eval[e;b] - : machine languageThe reader should have no occasion to use this functionas such, since it is called in by the APPLY operator, but hemight be interested in its modus operandi which is as follows,(b is' the list of pairs of bound variables) :evlis[x;b] : machine language-The function evlis Zs used by ' $he function eval above..The arguments of'-.evlis are a list, 5, of expressions, and alist, b, - of bound variables. The function evlis constructsa list of the values obtained by evaluating each element ofthe list x - J using - eval and the list - b, and the resultant list
