.SAVE

   This command, when used with the .RESTORE command, maintains the
   formatting context of a document for the user. The files produced
   by the DSR utilities make changes to the formatting context. In
   order not to disturb the user's context, the .RNT and .RNX files
   execute .SAVE and .RESTORE commands.

   The .SAVE command stores information about the current RUNOFF
   formatting context; this includes DSR defaults and DSR commands
   and flags issued by the user.

   The .RESTORE command restores the formatting information saved
   by the last-issued .SAVE command. .SAVE/ .RESTORE pairs may be
   nested up to 10 pairs deep.
