[Gambas-user] Gambas3 and Gnu scientific library

[Jussi Lahtinen]

Not me, it's John!
I have no need for other basic, even if I don't need GUI, Gambas is my
option.
Why not to do command line programs with Gambas!??

It's much easier and simpler!!!
This is all you need in Gambas:

Extern gsl_sf_bessel_J0(x As Float) As Float In "libgsl:0"

Public Sub Main()
  Print gsl_sf_bessel_J0(5)
End
