Global a As Integer, b&(1) As Long At MyData     Print b&(1) MyData:     DataLong 53214,100962

Remarks

Long, String, and Char variables require their suffix when declaring them. Only String variables can be resized using * <Size>.

Variables defined with At will be read only.

Global creates a variable that can be accessed in every scope. If you don't want the variable to be accessible everywhere, you can use the Dim command to limit the variable to the scope it is defined in.
