EDA is called by typing:
EDA then asks whether if you would like the news or not;
answer yes or no. There is also a possibility to get some
more information by typing EDA -HELP.
Only one printer is available. If the print file is opened
the program queries for a user message, which will be
printed on top of the listing produced.
A message giving
the name of the user should be used to allow for easy
identifying of the printed output. The print file name is
is the current time (6 characters).
This file is automatically spooled and deleted, unless the
NOPRINT parameter is present.
The EDAPLOT appendix is not available.
File errors: file errors normally are diagnosed with a
complete explanation given by the system in addition to the
EDA error message. A typical PR1ME error might be, that the
user does not have the necessary access rights to read/write
a file into the current UFD: in such a case enter the PRIMOS
interface and attach correctly, or use the PAUSE command and
attach on PRIMOS level.
Additionally there is a small interface to PRIMOS which is
called by typing an $ symbol in column 1. The following
commands are available:
ATTACH | ufd name |
| -HOME |
| -BACK |
The ufd-name specified can only be a next lower level ufd,
complete tree names are not allowed. The -HOME parameter
attaches to the LOGIN ufd. The -BACK parameter can be used
to step back one level of the hierarchy, but only if a
previous attach has been done using this interface. Full
advantage of this facility is therefore taken by starting at
the top level and working down from there.
QUIT returns to EDA
LIST [UFD] lists files in the current UFD
UFD lists only ufds.
PAUSE returns to PRIMOS, use START
to reenter EDA.
DELETE fname deletes file "fname"
If EDA terminates abnormally (zero-divide, crtl-P interrupt
etc.) you should issue a CLOSE ALL before reentering EDA
(try START 1000 if no external command has been done since
that event). EDA being a large segmented program, it takes
some time to load. The user should release his segments
from time to time by entering DELSEG ALL.
