	This UIC contains a traffic analysis program, and assorted
articles. 

	The largest contribution is ERLANG, a fortran program which
solves the Erlang B blocking formulas for traffic analysis. This is
very useful in wide variety of aplications where many users compete for
a limited resource, or wait on a single queue for one or more servers.
The subject is explained in a paper at the Fall 1982 symposium under
the somewhat misleading title of "Avoiding Congestion", and will be
given at the Spring 1983 symposium under the title "Sizing
Communications Requirements". The text is in this UIC as SIZCOM.DOC,
and in the proceedings and should be read before ERLANG.DOC, which
explains the program. 

	DOCPRP.DOC is a few notes on how to get your documentation in
a form which will be correctly transmitted on FLX tapes, such as
symposia collections, using TECO (even if you have never used TECO).
There is also a suggested procedure for recovering files which have
already been garbled, which also works for RT-11 tapes read on RSX.

	UT1.DOC is an article from the Multi-tasker on adding a user
translation table to MTAACP. 

	SORT.DOC is yet another comparison of sort timings: this one
done by actually running various Fortran sort routines on an RSX
system. If you are still using the Bubble sort, you are wasting your
time. See also "Internal sorting using Cobol-11 and Watbol-11" in the
Spring 1981 proceedings. 

	M8085.MAC is a version of the macro prefix file M8008.MAC in
the DECUS library. It allows assembly of 8080, 8085 and most Z80
programs with the regular PDP-11 Macro assembler by using M8085 as a
prefix. M8085.EXT is a version with user added routines (like
subroutine calls, push, pop, etc.) 

	PROM takes the output of the Macro Assembler (such as is
produced by M8085 above) and changes it to Intel MDS format for
transmission to a PROM programmer. 

	OTSMOD is a tool for making Fortran OTS module overlays. If a
Fortran-IV-Plus or Fortran-77 program is taskbuilt with the /MA switch
on the map, OTSMOD will extract the names of the OTS modules, eliminate
duplicates, and sort them alphabetically. This can then be used with
the ODL file distributed with fortran to overlay the OTS. 

	MULTI is a simple program to calculate throughput for one or
more processors sharing one or more memory banks. 

	QUERY.CMD creates an empty Datatrieve dictionary using RMSDEF.

	For those without a fortran compiler, task images which have
been built NOT using any resident libraries, and checkpointable, are
included, but you MUST have a floating point processor. Object modules
are not included as you must have the OTS modules to build the task,
and that is a DEC product. Although written in Fortran-77
(Fortran-IV-Plus), few extensions are used, and they should run or be
easily convertable to Fortran-IV. Comments on any of the above are
welcome.
