1162.0. "Null character in .lis file" by HYDRA::NEWMAN (Chuck Newman, 508/467-5499 (DTN 297), MRO1-3/F26) Wed Feb 05 1997 14:19

I compile -migrate -source_listing -machine_code to get a
listing file.  I tried doing dxdiff on a couple of these .lis
files and got a "syntax error" message from dxdiff.

Turns out there is a null character at the end of the listing
file name (with the -V option).  See it here as "^@" in the
following extract.

  -o    filename : test_fixup.o

1162.1I can see that too - but not in viTLE::WHITLOCKStan WhitlockWed Feb 05 1997 16:443
I see this with f77... we'll take a look and get it fixed.

Thanks			/Stan
1162.2Thanks. I can use vi and the w! command to "fix" the file.HYDRA::NEWMANChuck Newman, 508/467-5499 (DTN 297), MRO1-3/F26Thu Feb 06 1997 09:485
You don't see it in vi, but vi does tell you that there was a null character.
I used an NFS mounted disk and looked at it in EDT on OpenVMS.  A good DUMP
utility on Unix, if there were one, would have been another way.

    	I've analyzed the bug, and have passed it along the the
    right group.  There is no workaround I can see (the user has
    no way to affect the behavior).
    
    Cheers!
