The obvious; your claim is untrue and it is you.
Looks like you have egg on your face again.
Put up or shut up.
PL/I does not have computed GO TO.
If it looks like a duck, quacks like a duck, it probably is a duck.
Try:
GO TO X(I);
X(1): A = B;
...
X(2): A = C;
...
X(3): A = D;
...
and try:
GOTO (1, 2, 3), K
1 A = B
...
2 A = B
...
3 A = C
...
Guess which one is FORTRAN and which is PL/I.
It has LABEL arrays, which are more
useful. There may be cases where a computed GO TO would be clearer if
it exiasted, but good or bad, PL/I doesn't have it.
Read what I wrote.
I did; it's BS.
More egg on your face.
White space has noting to do with it.
That's a perfect example of BS. In FORTRAN, DO 500 I=1.10 is an
assignment statement because the blanks are not significant. In PL/I,
DO I=1.10; is still a DO statement, because spaces are not allowed
inside a variable name.
That is irrelevant to whether the DO statement in PL/I was taken
from FORTRAN.

especially as you cited things that don't even exist in PL/I as being
derived from FORTRAN.
Put up or shut up.
And you still haven't answered whether you
seriouslyu believe thaat the FORTRAN DO resembles the PL/I DO more
than the ALGOL FOR statement does.
Read what I wrote.
Your purported explanation of the difference in DO between FORTRAN and
PL/I is ludicrous, because the rules for "white spacew" in FORTRAN and
PL/I are very different.
White space has noting to do with it.
