If you are going to be doing work with assembly code and envision doing
any upgrades to a later version of HP-UX you should upgrade first.
In release 5.15, HP released 68020/68881 compilers, and we also at that
time released a new assembler.  That assembler was designed to have
a UNIX(*)-like assembler syntax.  The translator tools and assembly manual
referenced in previous responses to your note are for the 5.15 and after
assembler.  The 5.1 system predates the 68020 and 68881.  There is no
support for the addressing modes of the 68020 or for the 68881.

The note about reversed "cmp" arguments applies to the 5.15 and later
assembler -- done to follow what Motorola did with their UNIX(*) version
of their assembler.

In the 5.1 system, you have an "as" with the old/obsoleted HP-UX assembly
syntax, and a translator atrans(1) from the HP Pascal Workstation format
to 5.1 HPUX format.

In the 5.15 system, there is "as" with the new UNIX(*)-like syntax,
atrans(1) to translate from HP Pascal Workstation format to 5.15 format
and astrns(1) to translate pre-5.15 HP-UX format to the new HPUX format.

The HPUX Assembler Manual was written for the 5.15 and later releases.
