Unless I am mistaken the official term is deferred-length.
I have not yet tested this with my compilers, but I have reviewed the
implementation. I have very few comments about it:
- It is a pity that we cannot disambiguate on the deferred/assumed
length alone, but that is an issue of the language rules (the type of
"assumed-length character string" simply encompasses the type of
"deferred-length character string". Elaborate workaround might be possible,
using classes/derived types, but that is not worth the trouble I think).
- If we decide at some point that we need to keep the various
implementations, then perhaps we could "layer" the versions:
o The deferred-length variant can call the assumed-length + allocated size
variant
o This can in turn call the fixed size variant
It would reduce the amount of code, by a small amount of source lines. But
again, that may not be worth our while.
I should have time to test the implementation tomorrow. Maybe that will bring
out more comments ;).
Regards,
Arjen
