[Gambas-user] reading files

[nando_f at ...951...]

Yes it is possible, I do it.  here is some code (incomplete)

-Nando (Canada)



' top of class file
Public Struct recstruc
  _a as integer
  _b as integer
  _c as integer
end struct


' a function
public function openAfile(filename as string) as file

dim hfile as file
dim arec as recstruc

hfile = open filename for read write create

with arec   'some values to write.
  ._a = 1
  ._b = 22
  ._c = 333
end with

write #hfile, arec as recstruc

'if you position the hfile pointer back to zero, you can...
read #hfile, arec as recstruc

close #hfile

end
