No.  There are a couple of workarounds.  I've worked with this kind of 
stuff in the EDI realm.

1 - What is often done in EDI is that you would break this up into three 
physical files.  Then you would use a 'multiformat logical file' to bring 
them all back together again.

2 - You could create three new 'shell' physical files that would never 
contain data.  When you read from these files you can read into a data 
structure.  You would use these shell files to create 3 externally defined 
data structures.  Or if shell files burn your shorts just create three 
different internally defined data structures and read into that.

3 - Leave it the way it is.

Why you are changing what is working has a major bearing on which solution 
to recommend.
