no !
 public TYPE tutype
   mystring as string[32]
   mySTaticarray[12] as integer
 end type
 public TYPE montype
   mystring as string[32]
   mySTaticarray[12] as integer
   mytutipe[3] as tutype
 end type



dim myudt as UDT.Montype

mydut.mystring="hello"
myudt.mystringarray[0]="coucou"
myudt.mytutipe.mystring = "word"


or

TYPE StringData
Name as string * 10
FirstName as string *10
END TYPE
dim myString data as stringdata
Read #file, MystringData, TypeLen(MyStingData) 'who is = to 20

in the file :
'Bodard    Fabien    '

now i can draw a function  in gambas like :
FileRead(File as stream, type as type, n)
(chhht!! it's fread in c in fact)

but i like the idea to have the capability to load ad save binary data in one 
time like in C.
