Hi
 Using the Postscript like concept, one would have a compactor
word defined earlier in the file such that simple syntax like:

 EXPAND 512 E5 would be able to create a block of 512 E5's

 Of course one might want to keep a consistant radix like:
 
 EXPAND 200 E5
 
 But that is not neccessary if the word EXPAND was first defined
as such.
 Also such things as copy protection where a sector size has
been changed on a track might be encoded as:

 SECTOR_SIZE 512 SECTOR_DATA 0 xxx..xxx SECTOR_SIZE 256
 SECTOR_DATA 1 xx....xxx etc.
 
 The Archive file could include a simple glossary of the externally
defined words that are in common use while still being internally
extended to cover special cases.
