GET (File I/O) Statement Programming Example
 
The following program opens the file TESTDAT2.DAT for random
access and displays the contents on the screen.
 
'  Read and display the contents of a file containing a
'  name of up to 20 characters and a test score.
'
'  Define record fields.
TYPE TestRecord
   NameField  AS STRING * 20
   ScoreField AS SINGLE
END TYPE
' Define a variable of the user type.
DIM Rec AS TestRecord

' This part of the program is an insert whose only function is to
' create a random-access file to be used by the second part of the
