Yes, that's fine. I just wanted to mention it as you talked about using 
it as actual argument to "INTENT((IN)OUT)" - thus I wanted to make sure 
this usage case does not get forgotten.

Translating individual strings without context is difficult - it it 
might happen that, e.g., "expression" occurs twice. If you then need an 
article, you might be in trouble, e.g.
"... to an expression ..."  vs. "... to a vector-indexed target"
Where to place the article? In the long string you cannot as it is 
depends on the term which is in "%s". And for "expression" you only can 
do it if (a) you realize that it is used in the context above and (b) 
when "expression" is not used elsewhere.

I think in general, we do not give much help to translators with our 
strings. I think it is possible to annotate the strings and thus helping 
the translators to understand the terms, e.g. "dummy" or "parameter" 
might be wrongly interpreted by compiler/computer science translators 
without Fortran background.

Have a look at gcc/po/gcc.pot to see how it looks from a translator 
perspective and note (a) how many strings they have to translate (namely 
7865), how many terms are used multiple times (i.e. multiple files 
listed for a single mesgid), and how few strings have a comment above to 
help the translator (Answer: Essentially none; there are comments 
[search for "#."] but they are for the programmers and not for the 
translators). -- I think we should try to improve the translator 
comments ...

Yes.
