Dim varname as someUDT At pMem

[ReneMiner]

Problem as follows:

I create from pb-module a new UDT, like

Local myUDT, myData as String
 
myUDT="Type t_Test" & $CRLF & _
             "lNum_A as Long" & $CRLF & _
             "lNum_B as Long" & $CRLF & _
             "bX As Byte" & $CRLF & _
             "bY As Byte" & $CRLF & _
              "bZ As Byte" & $CRLF & _
             "End Type" & $CRLF

I have some data in memory, to simplify it in this example i use a string here

myData = MKL$(1000) & MKL$(2000) & " @`"  ' = 32, 64, 96

' then i create the udt in thinbasic through the module:

thinBasic_AddUDT(myUDT)

now i am stuck!
How can i dimension from pb-module an absolute tb-variable of t_Test at StrPtr(myData) ?
