318	Remove several excess segments from Multics Libraries	Gary Dixon	Eric Swenson	"MCR10140 proposed enhancement to mbuild to support installing compose Device Writer programs and library expansion segments (suffixes:  .pl1.xdw  and  .xdw  respectively).  If this proposal is accepted, then the following segments should be removed from the Multics Libraries.

* >unb>comp_dev_writer.xdw
* >ldd>unb>source>bound_xerox_dsm_.s.archive::x9700_writer_.pl1
* >ldd>unb>source>bound_hyterm_dsm_.s.archive::hyterm_writer_.pl1
* >ldd>unb>source>bound_ascii_dsm_.s.archive::ascii_writer_.pl1

The first of these segments is not an executable, but can be classed as a ""compose Library Expansion segment"".  It is currently installed in two places:


{{{
lpn comp_dev_writer.xdw
>ldd>unb>source>comp_dev_writer.xdw
>unb>comp_dev_writer.xdw
}}}


The MCR10140 proposal for installing this segment using mbuild calls for its installation only in the >ldd>unbundled>source directory.

The remaining files in the list above are derived source files created by expanding a compose Device Writer program source file (suffix:  .pl1.xdw).  Both their original source segment and the derived source are installed as components in their bound object's source archive.


{{{
lpn *.pl1.xdw [strip_component ([lpn *.pl1.xdw]) ]
>ldd>unb>source>bound_xerox_dsm_.s.archive::x9700_writer_.pl1
>ldd>unb>source>bound_xerox_dsm_.s.archive::x9700_writer_.pl1.xdw
>ldd>unb>source>bound_hyterm_dsm_.s.archive::hyterm_writer_.pl1
>ldd>unb>source>bound_hyterm_dsm_.s.archive::hyterm_writer_.pl1.xdw
>ldd>unb>source>bound_ascii_dsm_.s.archive::ascii_writer_.pl1
>ldd>unb>source>bound_ascii_dsm_.s.archive::ascii_writer_.pl1.xdw
}}}


MCR10140 proposes installing only the .pl1.xdw original source segments, and discarding their derived .pl1 source segments after they are compiled by PL/I.  Only the objects generated by the pl1 compile would be added to the object archive.


{{{
lpn *.pl1.xdw [strip_entry ([strip_component ([lpn *.pl1.xdw]) ]) ] -lb s -lb o
>ldd>unb>source>bound_xerox_dsm_.s.archive::x9700_writer_.pl1.xdw
>ldd>unb>source>bound_hyterm_dsm_.s.archive::hyterm_writer_.pl1.xdw
>ldd>unb>source>bound_ascii_dsm_.s.archive::ascii_writer_.pl1.xdw
>ldd>unb>object>bound_xerox_dsm_.archive::x9700_writer_
>ldd>unb>object>bound_hyterm_dsm_.archive::hyterm_writer_
>ldd>unb>object>bound_ascii_dsm_.archive::ascii_writer_
}}}

Because these ""extra segments"" violate the mbuild installation rules, they must be manually removed from the Multics Libraries using an update_seg exec_com created manually.
