SUBTTL DEFINITIONS -- Prototype SCAN Block
;THIS DEFINITION FOR THE S.xxxx BLOCK IS USED BY SORT AND SCAN TO KEEP TRACK OF
;FILE SPECS. AS SCAN READS FILE SPECS, IT ASKS SORT FOR MEMORY IN WHICH TO STORE
;THEM. SCAN REQUIRES ONLY THOSE LOCATIONS FROM S.DEV ON, SO THE REST IS FOR SORT
;TO LINK THE BLOCKS TOGETHER AND TO STORE SORT'S SWITCH ARGUMENTS IN.
