[Gambas-user] Errotr message " Illegal seek"

[Mr. Robert]

Firstly, a Line # of where the error occurred would help, but i'm guessing
its where it tries to READ.
 I'm no expert unfortunately, but a quick 'guess' response would be that
when using READ with streams, the position is incremented by 1, so when you
try to read again, you are not reading from the start, but rather the next
byte after your previous read, which seems to be unavailable. I'm not sure
if Gambas has a SEEK function, but if it does, you need to use it to "reset"
your position in the file to 0 (or 1 depending, probably 0).
