Tristan,
The Intel's assembler port onto VMS has a -Nvms_upcase option to
preserve symbols casing. If no
- -Nvms_upcase symbols are upcased. The as GNU assembler on OpenVMS has
no such.
Read the USAGE EXAMPLES I just added to my article at
http://vouters.dyndns.org/tima/OpenVMS-binutils-2.21.51-Unix_utilities-nm-strings-size-addr2line-objdump-as_on_OpenVMS.html
You'll find a comparison between as.EXE and Intel's iasi64.EXE
Best,
Philippe
