Consider the following code.
```
character(13) c
real r1(3), r2(3)
integer i1, i2
c = '1.2, 1.2, 1.2'
write (2, '(2a)') c, ' '
write (3, '(2a)') c, ','
rewind 2
rewind 3
read (2, '(3F5.1)', advance='no', size=i1) r1
print*, i1
read (3, '(3F5.1)', advance='no', size=i2) r2
print*, i2
end
```
XLF returns
```
12
11
```
Because we count the blanks but not the comma. So the first read is 3 records of `1.2 ` that has 4 characters. The 2nd read is 3 records with the first two being `1.2 ` and the 3rd one `1.2` (without blank because of the comma appended.
gfortran is consistent with XLF.
ifort outputs
```
14
14
```
ifort seems count everything including blanks and the commas.
Flang outputs
```
9
14
```
It seems inconsistent to me.
I am clarifying with J3, but it seems comma should not be part of the input field.
