No. Well, at least not in the interpreter. The symbols in the LISP
1.5 dictionary were:
$ $ALIST $EOF$ $EOR$ $IL15$ $IL16$ $IL17$ $IL32$ $IL35$ $IL36$ $IL37$
$IL52$ $IL55$ $IL56$ $IL57$ $IL75$ $IL76$ $IL77$ ( ) * *LIST *MOVE
*RETURN + , - . / = A ADD1 ADVANCE AND APPEND APPLY APVAL
ARRAY ATOM ATTRIB B BLANK C CAAAR CAADR CAAR CADAR CADDR CADR CAR
CDAAR CDADR CDAR CDDAR CDDDR CDDR CDR CHARCOUNT CLEARBUFF COMMA COND
CONS COPY COUNT CP1 CURCHAR D DASH DIFFERENCE DIGIT DIVIDE DOLLAR DUMP
E END ENDREAD EOF EOR EQ EQSIGN EQUAL ERROR ERROR1 ERRORSET EVAL EVLIS
EXPR EXPT F FEXPR FIX FIXP FLOAT FLOATP FSUBR FUNARG FUNCTION G GENSYM

SPECIAL STAR STARTREAD STOP SUB1 SUBLIS SUBR SUBST SYM T TEMPUS-FUGIT
TERPRI TIMES TRACE U UNCOUNT UNPACK V W X Y Z ZEROP
(The 1-character symbols were used as _characters_, there was no
string or character data type, only symbols. The symbols named $ILxx$
are illegal (non-printable) characters. Their actual names are the
characters whose code is given by the digits xx.)
The "REPL" of the LISP 1.5 (on 7090) was EVALQUOTE: it read two forms,
the first being a function, and the second a list of arguments, and it
applied the first to the second, in effect QUOTE-ing automatically the
arguments.
If I've understood correctly, it read a form.
If it's the symbol STOP, it returns to the OVERLORD.
If it's another symbol, then it reads a list of arguments and
applies the function to the list of arguments (unevaluated, ie, as
if quoted). You'd punch:
CAR ((A B C D))
for: (CAR (QUOTE (A B C D)))
If it was a list, then it was take as a definition:
(ACONS (LAMBDA (K V A) (CONS (CONS K V) A)))
to define a function ACONS.
