Dear Jean-Yves,
basic is not stupid C. If C doesn't distinguish between strings and
arrays, well, many others do, including gambas.
I can't remember well, but I think that you can't change a single
character in a string - you must use MID$() and & to extract the left
part, add the changed part, and add the last part. Something like:
global.last.selection = "W" & mid(global.last.selection,2)
(there is no left part to preserve) ...but read about mid$(), I am not sure.
Perhaps you are thinking that gambas is stupid, but this way you can
collect a single character, or many, while in C you use two different
methods ([...] access and strcat() and so on).
Regards,
Doriano
