There seems to be a bug with regards to S:
print "(s,F0.2)", inf
still prints "+Inf". ("The edit descriptors SS, SP, and S set the sign mode
corresponding to the SIGN= specifier values SUPPRESS, PLUS, and
PROCESSOR_DEFINED, respectively.")
"(6) On output, with I, B, O, Z, F, and G editing, the specified value of the
field width w may be zero. In such cases, the processor selects the smallest
positive actual field width that does not result in a field filled with
asterisks" (10.7.2.1 General rules)
I have to agree with Thomas here: ".00" and "Inf" are the shorted possible
strings, unless SP (sign="PLUS") is used; then "+.00" and "+Inf" are the
shortest possible strings.
In that sense, none of my 10 compiler gets it right ...
