C   VALUE   RETURNS A DATA ITEM VALUE IN THE IARG ARRAY.
C     IF THE VALUE IS IN THE PART OF QSKIB THAT IS CURRENTLY
C     IN CORE (IN IMA AND IB BUFFERS) THEN THE VALUE IS TRANSFERRED 
C     DIRECTLY FROM IMA STARTING AT POSITION IOFF. IF THE VALUE 
C     IS NOT IN THE PART OF QSKIB CURRENTLY IN CORE, THEN THE 
C     PART OF QSKIB CONTAINING THE VALUE IS READ INTO IMA, AND
C     THE TRANSFER EFFECTED.
C 
C   CALLING PARAMETERS: 
C    IARG  - THE ARRAY IN WHICH THE DATA ITEM VALUE WILL BE RETURNED
C    ISEC  - THE STARTING SECTOR NUMBER OF THE QSKIB BLOCK WHICH
C     CONTAINS  THE VALUE. ISEC RETURNS THE SECTOR OF THE NEXT VALUE. 
C    IOFF  - THE WORD OFFSET OF THE VALUE,FROM THE BEGINNING OF ISEC
C     IOFF RETURNS THE OFFSET OF THE NEXT VALUE 
C 
C     DEFINITION OF SYMBOLS 
C    QSKIB  - THE TRACK CONTAINING DATA ITEM VALUES. EACH VALUE IS
C     PRECEEDED BY ITS WORD LENGTH.(IF THE LENGTH IS NEGATIVE, THE
C     VALUE IS A DUPLICATE KEY ITEM VALUE)
C    IQSEC  - THE NUMBER OF SECTORS OF THIS IN-CORE BUFFER (IMA AND IB
C             BUFFERS ARE LONG ENOUGH FOR SEVEN PHYSICAL DISC SECTORS 
C             WHERE EACH SECTOR IS 128 WORDS LONG)
C    IMA  - THE BUFFER CONTAINING PART OF QSKIB. IF QSKIB IS NO LONGER
C     THAN IBSZ, ALL VALUES ALWAYS REMAIN CORE IN IMA AND THE 
C     VALUES ARE NEVER REALLY IN QSKIB. (NOTE:THE BUFFER CONSISTS OF
C     THE IMA AND IB ARRAYS WHICH MUST ALWAYS BE ADJACENT)
C     TRKNM - THE TRACK NUMBER OF QSKIB 
C       NOTE: THE STARTING SECTOR NUMBER OF THE CURRENT BLOCK OF
C     QSKIB PRESENTLY IN CORE IS CONTAINED IN SECNO
