when they say 'modern' fortran i take it to imply a a compiler and standard from sometime in the last 20 years.

i've heard people refer to c90 as modern before.. (in the last two years) and the nasa/astronomy guys are famously clingy to 'known good' tech from the olden days.

only the very most recent astronomical dataset i acquired was in .csv. everything is made for fortran from what i've seen over the last 10 years...
