The following is the Compilation and Linking Procedure for NELS V21
for a VAX- based system

$fortran/extend nels21
$fortran/extend ngraph
$link nels20,ngraph
$rename nels20.exe nels.exe
$run nels

NOTE: you must have current versions of the ATMLVL.TBL file
and for the program to implement all options. You should also
create the terminal data file TERMIN.DAT for the graphics utilities.
for further information on these see EMMPDL entries NGRAPH, ATMLVL.

A preliminary set of instructions for the NEDS/NELS series of data
(spectral analysis programs follows.  



             Preliminary Instructions for NELS VERSION 21

            ----------------------------------------------



The program is started entering the normal RT-11 operating mode.  When
the (.) appears indicating RT-11 is ready enter the following


                        .RUN NELS <CR>  

                              or

                        .RUN DY1:NELS <CR>


where <CR> means to enter a carriage RETURN.   For  Vax-based  systems
you  need  only  enter  RUN  NELS after your system prompt.  The RT-11
device specification DY1:  is only necessary if your copy of  NELS  is
stored  on  DISK  DRIVE  1  instead  of the system DISK (DY0:) as most
software is normally stored.  You should also  insure  that  the  file
ATMLVL.TBL  exists and is on the system DISK.  You should refer to the
EMMPDL files on this subject for further details.

Before  running  the  program  you  should  first  inspect  the   file
DK:TERMIN.DAT  by typing it out on the crt display.  This file is read
by NELS and determines the characteristics of your  terminal  relative
.to this program.  If the characteristics of your terminal (type and/or
baud rate) are different  than  those  listed,  then  use  the  normal
.VAX/RT-11 EDITOR to change the terminal type (i.e.  0,1,2,3 as defined
in the file), and the baud rate.  NOTE:  donot  erase  any  text  from
this  file  as it important in the field specifications.  A listing of
this file is given below:

The current terminal configurations  is  by  the  above  an  INTECOLOR
VT-100 with Tektronics 4027 graphics, operating at 9600 BAUD.



The program begins by  initializing  the  display,  printing  out  the
current  version number, date etc.  and the hardcopy output file name.
For VAX based systems this is the default output device FOR008.DAT.

The program next types out the general Menu of available commands  the
operator  need  only  type  in the corresponding two character code to
select an option.  Hopefully, most of these will be  selfexplainitory.
A list of the current Menu is given below


         GR = GRAPH MODIFICATION OF DISPLAY
         WI = WINDOW SET AND EXPAND TO FILL DISPLAY
         CU = CURSOR VALUE
         SM = SMOOTH DATA
         CA = CALIBRATE SPECTRUM
         NO = NORMALIZE (REMOVE) GAIN CHANGES
         BG = BACKGROUND FITTING
         IN = INTEGRATE EDGE
         DF = DIGITAL FILTER OF THE SPECTRUM
         ME = MEMORY AND  DATA MANIPULATION
         RE = READ DATA FILE FROM DISK
         WR = WRITE DATA TO FILE ON DISK
         OR = ORIGINAL DATA REDRAWN
         EX = EXIT PROGRAM
        
         THE FOLLOWING MODES ARE AVAILABLE IN THE "ME" OPTION
        
         CO = COPY FROM MEM  1 TO 2 OR 3
         SS = SPECTRUM-SPECTRUM MATH +,-,X,/ MEM 1 BY MEM 2
         SC = SPECTRUM-CONSTANT MATH " " " " MEM 1 BY CONSTANT
         LO = LOG OF DISPLAY
         AL = ANTILOG OF DISPLAY
         OV = OVERLAY MEM1/MEM2 ETC.
         ZE = SETS ALL VALUES <0. IN CURRENT MEMORY = TO 0.
         DE = DELETE PORTION OF CURRENT MEMORY
         EQ = EQUALIZE (SCALE) 2 MEMORIES AT CURSOR LOCATION
        
        
After listing the options the program automatically  requests  you  to
supply  a  EMMPDL  DATA  FILE  for  input.  Use the demonstration file
NIO.001 if you donot have a suitable spectrum available.  Please  note
that  this  program only reads data in the EMMPDL file format, if your
data file is of a different format (ie.  EDAX, KEVEX,  ORTEC,  TRACOR,
PGT,  LINK  etc.)  this  program will not accept the data files as is.
The program NTRAN will translate some of this data  to  EMMPDL  format
and  vice-versa  and  you  must run it first.  The subroutine RPDL.FOR
documents the expected  data  file  format  for  those  interested  in
writing  their  own  translation  routine, however, I would appreciate
comments and/or information concerning other data formats inorder that
I can keep NTRAN up to date for all users.

At this point the program enters  its  general  command  sequence  the
usual series of steps in an analysis would be something like this:


 1.) RECALL SPECTRUM (if present data is not suitable)
 2.) CALIBRATE, and MODIFY SPECTRUM USING DISPLAY MANIPULATION OPTIONS
 3.) NORMALIZE  (if gain changes are present between edges)
 4.) FIT BACKGROUND CURVE FOR 1ST ELEMENT (lowest energy first!)
 5.) INTEGRATE 1ST ELEMENT 
 6.) FIT BACKGROUND CURVE FOR NEXT ELEMENT
 7.) INTEGRATE (repeat lines 5 - 7 for each element)
 8.) EXIT PROGRAM
        
        
                           General Remarks
                           ---------------

This version of NELS exclusively uses memory 1 for data and  memory  2
for  calculations  and/or backgrounds.  The maximum spectral size that
the current program can support is 4096 channels in 3  memories  on  a
Vax  system,  or  with  appropriate  modification  1024  channels in 3
memories on a RT-11 system.  Remember that  some  routines  modify  or
even  delete portions of the spectrum so always store the spectra on a
DISK FILE before analyzing it.
                                 GRPH
                                 ----
This is the general display control routine which allows the  operator
to  redraw  the current display.  This should be used when the display
gets too messy due to multiple operations or you just  wish  to  erase
the  entire  screen  and start over.  Its options are few, but must be
entered  in  the  following  order   OVERLAY(Y-N),Y-MAG,SYMBOL(-9   to
+1)<CR>.   Here  the  OVERLAY  options  allows the user to superimpose
ontop of the current display a modification of the present  display  .
Thus  by specifying a Y-MAG the user can expand the display to look at
a small feature of interest.  SYMBOL refers to  the  various  plotting
symbols  +1=  line,  0=  dots,  etc.  (-9 = solid fill and is good for
photography).   A  typical  answer  sequence   would   therefore   be:
Y,3.,+1<CR>  or  N,1.,-9<CR> Remember the commas here are essential to
seperate command inputs!!.
