This example opens a file (random-with-fixed-header.dat) having the following contents :
This is a fixed-length header!Record01Record02Record03
The string "This is a fixed-length header!" is the header
It contains 3 records, "Record01" through "Record03", of length 8.
The script then displays :
- The header contents
- The number of records
- Each individual record
