Ethymology of Alphabetic Keywords (and builtin math ops)

Disclaimer: This list is very incomplete.

abs: ``early'' Fortran, Algol 60 [TSPL]
access: pointer type constructor in Ada
array: datatype constructor in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
begin: Algol 58[ref], 60[TSPL]
bits: datatype in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
bytes: datatype in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
bool: in Algol 60 [Cardelli, Wegner, 1985: UTDAP]
case: the case statement in Pascal 72 [mentioning (1 2]
The case statement is the language design proposal which Hoare is "still most proud of" [PLCC 99, refering to Hoare: The emperor's old clothes; 75-83 Communic. ACM 24:2, 1981].
char: in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
class: Simula 1967 [Sim]
cluster: for an ADT implementation module in CLU 1977 [PL]
continue: (e.g. at end of for-loop) to force next iteration of for-loop in Fortran 1957 [PL]
dimension: ``early'' Fortran [TSPL]
do
1. instead of "for" in ``early'' Fortran [TSPL]:
```
		   DO 20 I = 0, 2*Nmax
		   ...
		20 CONTINUE
```
  [PL]
2. in "for ... do ...": Algol 60 [TSPL]
E: in floating point numbers:
1. ``scientific notation'' with floating decimal point was introduced by John Napier (1550-1617, Scottland). But did he use "E" ???.
2. Algol 60, 1958-60 [HN].
else: Algol 60 [TSPL]
end: Algol 58[ref], 60[TSPL]
except: to handle exceptions in CLU 1977.
exports: for the export list of Euclid's instantiable modules 1977 [PL]
file: datatype in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
for: Algol 60 [TSPL]
format: datatype in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
go: ``early'' Fortran [TSPL]
if: ``early'' Fortran, Algol 60 [TSPL]
in: for dynamic type-test: Simula 1967 [Sim]
int: in Algol 60 [Cardelli, Wegner, 1985: UTDAP]
OR was it integer in Algol 60 [TSPL] ???
module: for an instantiable module with component types, procedures and export list in Euclid 1977 [PL]
print: ``early'' Fortran [TSPL]
proc: datatype constructor in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
procedure:
1. definition constructor in Algol 60 [TSPL]
2. type of any procedure (eg as parameter) in Algol 60 and original Pascal [ref]
qua: for dynamic type-cast: Simula 1967 [Sim]
real: in Algol 60 [TSPL; Cardelli, Wegner, 1985: UTDAP]
ref: datatype constructor in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
signal: to raise exceptions in CLU 1977.
sqr: for squares (instead of Fortran's "**"): Pascal 1971/72 [HN].
sqrt: for square roots: ``early'' Fortran, Algol 60 [TSPL]
step: Algol 60 [TSPL]
stop: ``early'' Fortran [TSPL]
string: in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
struct: datatype constructor in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
switch: ``the horrid Algol 60 switch''
then: Algol 60 [TSPL]
to (in "go to ..."): ``early'' Fortran [TSPL]
union: datatype constructor in Algol 68 [Cardelli, Wegner, 1985: UTDAP]
until (in "for ... until ... do ..."): Algol 60 [TSPL]
value: Algol 60 [TSPL]
virtual: for object operations with implementation deferred to subclasses: Simula 1967 [Sim]
