In a private communication, someone at JPL suggested a better fix for
the nonstandard Fortran in BINMERGE. Replace

READ(nfil,REC=NREC,END=6,ERR=98)(DATA(K),K=1,NDATA)

with

READ(nfil,REC=NREC,IOSTAT=ISTAT)(DATA(K),K=1,NDATA)
IF (ISTAT .EQ. -1) THEN
GO TO 6
ELSE IF (ISTAT .NE. 0) THEN
GO TO 98
END IF

Leave the rest of the program unchanged.

My correspondent said the BINMERGE source code online at the FTP site
will be rewritten to eliminate this problem.


The other problem, the modification needed by the ASCII conversion
program in order to process DE406 files, seems to be history. An
improved ASC2EPH now available for download seems to be a universal
converter. At least, it checks out ok with DE405 and DE406 on my
Windows system.
