See:
"13.7.76 MIN (A1, A2 [, A3, ...])
For arguments of character type, the result is the value that would be selected
by application of intrinsic relational operators; that is, the collating
sequence for characters with the kind type parameter of the arguments is
applied. If the selected argument is shorter than the longest argument, the 20
result is extended with blanks on the right to the length of the longest
argument."

"Example. [...] MIN (”A”, ”YY”) has the value “A “, and
22 MIN ((/”Z”, ”A”/), (/”YY”, ”B “/)) has the value (/”YY”, ”A “/)."

Analogously for:
"13.7.71 MAX (A1, A2 [, A3, ...])"

Confirmed.

Tobias,

What criterion are you chosing for the missing F2003 features?  The reason that
I ask is that it is not clear to me when you stop; eg. should we have a PR for
polymorphism or for sub-modules?  Maybe it would be better to have a meta-bug
for F2003 and point to a Wiki page in which we try to joggle up a priority
order?

Best regards

Paul
