[Gambas-user] OpenGL's getString(mode) not returning string

[terco IDE]

Hi all:

the openGL funcion

getString( name ) as string

gives error when using it like:
Dim s As String
  s = gl.GetString(gl.VENDOR)

Error: not returning value

as if were defined like a sub

I'm using Gambas 3.5.90

Saludos
Martin
