C Edit History:
C
C Edit (%O'3', '16-Oct-82', 'David Dyer-Bennet')
C %( Add fortran interface tests: FOR36 V6 (F6T1.FOR), FOR36 V7 (F7T1.FOR),
C FOR32 V3 (F32T1.VAX-FOR). F7T1 has the detailed justification
C of the source and expected destination values used. )%
C
C Edit (%O'12', '07-Dec-82', 'Sandy Clemens')
C %( Change VAX fortran interface test to use "6" for output device
C rather than "5", in order to make VAX batch stream work.
C File: FT32T1.VAX-FOR )%
C
C Edit (%O'14', '14-Jan-83', 'Sandy Clemens')
C %( Many edits to the Installation Verification system (ICS) files.
C Add SYS: to all the 10/20 programs in the COPY or INCLUDE
C statement for the interface files. Add SYS$LIBRARY to the VAX
C programs in the COPY or INCLUDE statement for the interface
C files. Add check for INFO or SUCCESS status return in all ICS
C programs. Add Lib$Match_Cond to VMS programs for status
C checking. Change some of the symbolic variable names for
C clarification. Change use of numeric parameter values to
C symbolic variable names. Get rid of use of "IMPLICIT INTEGER"
C in FORTRAN test programs. Add copyright notice to everything.
C Make the TOPS-10 test programs EXACTLY the same as the TOPS-20
C programs, in order to use the same ones on both systems. Files:

C Since our source data has only 26 bits of precision, we won't get
C more than that as the result of our conversion. In fact, the first
C word will hold 24 bits of mantissa (including the hidden bit),
C and only two will overflow into the second word. Of those two,
C the second is 0. Thus, the second word of the D_Float will only
C have the one bit set. See diagram of D_Float for why it's the
C bit it is, buried in the middle of the word. Or take my word for it.
