Re: [Gretl-devel] getenv(): about environment strings

Dear all,
I just try the following envioenment strings with the hansl script below
under winXP.
I testes with both gretl 1.10.90cvs and 1.10.1. The results turned the
same. It looks that many of the strings returned null strings. Is this what
sven said "... wasn't able to get anything out of it?"
Thanks

True, there's not much stuff relevant to gretl in the Windows
environment. Variables such as 'gnuplot' and 'tramo' are available as
gretl strings, either proper string variables (e.g. $gnuplot) or as
string-substitution targets (e.g. @gnuplot).
It shouldn't be too difficult to provide a gretl $lang accessor. I'll
take a look at that and report back.
