UDT, Strings and Pointers. . .

"it looks a little wierd"

I have a binary file, which includes different arrays of different types. Dimension is variable and I can't declare Type or to do like in VB Get array.
So I read information into fixed-length(!) String and use pointers similar you:
DefInt A-Z
...
Dim IntegerPtr As Double Ptr
Dim SinglePtr As Single Ptr
Dim DoublePtr As Double Ptr
....
%LenTmpBuffer = 512
Dim TmpBuffer As String * %LenTmpBuffer
PosMaxTmpBuffer& = VarPtr(TmpBuffer) + %LenTmpBuffer
IntegerPtr = PosMaxTmpBuffer&
...
Dim mdir(0 To n)

For i = 0 To n
If IntegerPtr >= PosMaxTmpBuffer& Then Get #1, , TmpBuffer: IntegerPtr = VarPtr(TmpBuffer)
mdir(i) = @IntegerPtr: IntegerPtr = IntegerPtr + 2
Next

Also looks more than strange, but works.

Is it OK to change this:

Type myudt
lweapon(1 to 10) As Long
sweapon(1 to 20) As Long
End Type
Global tt As myudt
Dim i As Long
For i = 1 to 20
tt.sweapon(i) = tt.sweapon(i) + 1
Next i

To This:

Type myudt
lweaponS As String * 40
sweaponS As String * 80
End Type
Global tt As myudt

And then access the data like this:

Dim vPTR As Long PTR
Dim i As Long
vPTR = VARPTR(tt.sweaponS)
For i = 1 To 20
@vPTR[i - 1] = @vPTR[i - 1] + 1
Next i

Did I break any written or unwritten power basic programming rules?

My program that I am doing this in runs great, I am unable to detect
any errors. I have just never used pointers like that before, it looks
a little wierd, is it OK?
