C ABSTRACT: 
C 
C  SCAN SKIPS ALL INPUT UNTIL THE REQUESTED "TYPE"
C  IS RETURNED FROM GGLOB, OR UNTIL A 
C  "END." COMMAND OR A SEMICOLN IS DISCOVERED.
C  WHEN THE REQUESTED TYPE IS FOUND, THAT RESNO 
C  IS SKIPPED, AND THE INPUT STREAM IS POSITIONED PAST IT.
C 
C CALLING SEQUENCE: 
C 
C      CALL SCAN(ITYP)
C 
C        WHERE: 
C 
C         ITYP
C         IS A LEGAL TYPE NUMBER.  SEE "GGLOB" FOR THE LIST 
C         OF LEGAL TYPES AND THEIR MEANINGS 
C 
C ON EXIT:
C 
C      IF AN "END." COMMAND IS FOUND, SCAN TERMINATES DBDS !!!! 
C      OTHERWISE, SCAN STOPS ON A SEMICOLN OR THE REQUESTED TYPE. 
C 
C      IF A SEMICOLN WAS FOUND BEFORE THE REQUESTED TYPE, 
C      SCAN STOPS ON THE SEMICOLN, OTHERWISE SCAN STOPS ONE CALL
C      TO "GGLOB" PAST THE REQUESTED TYPE.
C 
C      SCAN IS USED TO FIND THE END OF A COMMAND LINE, IE. TO SEARCH
C      FOR A SEMICOLN, OR SCAN IS USED TO FIND THE NEXT COMMAND 
C      SUCH AS "ITEMS:", OR "SETS:".
