LEADS DATA BASE SOFTWARE
DISTRIBUTION #1
01-JUN-1978


THIS IS THE FIRST RELEASE OF THE PROJECT LEADS DATA BASE SOFTWARE
AND THUS REPRESENTS THE STATE OF THE PROJECT WHEN
FUNDING WAS TERMINATED.

POTENTIAL USERS ARE REMINDED THAT AT THE PRESENT TIME, THERE
IS NO FORMAL SUPPORT FOR THIS SOFTWARE.  THE SOFTWARE IS IN
DAILY USE IN SEVERAL SCHOOL SYSTEMS, BUT EACH USE IS "ON
HIS OWN" WHEN A PROBLEM OCCURS.

BECAUSE AT LEAST ONE MAINTENANCE/ENHANCEMENT RELEASE IS 
PLANNED FOR THE NOT YET SPECIFIC FUTURE, YOUR COMMENTS,
PROBLEMS AND QUESTIONS ARE ENCOURAGED EVEN THOUGH WE CAN
NOT GUARANTEE AN ANSWER OF ANY TYPE.  PLEASE SEND ANY SUCH
QUERIES TO: COMPUTER SERVICES; LEXINGTON PUBLIC SCHOOLS;
251 WALTHAM STREET; LEXINGTON, MASS. 02173.

DOCUMENTATION IS CURRENTLY IN FOUR MAJOR MANUALS.  THE
"LEADS OVERVIEW" IN HARD COPY FORM SHOULD ACCOMPANY THIS
DISTRIBUTION PACK.  (NOTE: THE "HISTORY FILES" DESCRIBED
IN THE OVERVIEW HAVE NOT BEEN IMPLEMENTED.)  THE OTHER THREE
MANUALS ARE IN ACCOUNT 200,14 OF THIS PACK.  THESE SHOULD BE
LISTED ON 80 COLUMN PAPER, PREFERABLY WITH LOWER CASE
OUTPUT.  THE "DATA BASE MANAGER'S MANUAL" SHOULD BE READ
BEFORE!!! ATTEMPTING TO INSTALL A LEADS DATA BASE.

GOOD LUCK!!


To install the Project LEADS Software on your RSTS/E system,
you must COMPLETE the following steps:

   1) Create two directories;  they will contain the executable 
      programs (.BAC) and the required source files for certain
      operations (.BAS, .LTX, .VCA, etc.).  

   2) Install system-wide logical names for these directories using
      the UTILTY system program.  These names are as follows:
      
	LEADS:  contains the executable object code
	PUB:    is the system library account ($).
	LEADS0: is the source-file directory.

      It is suggested that the START.CTL and CRASH.CTL command
      files be changed to install these LOGICAL NAMES
      at system start-up time.

      At this time, you may also wish to add lines TO THE START.CTL
      FILE WHICH WILL log in an extra priveleged job TO run the
      program PUB:LOGGER.  This will allow for the logging
      operations described in the LEADS data base managers'
      manual.  If this is not done, there is no reason to
      install the supplied UMOUNT.


   3) For each file in account [1,2] on THE DISTRIBUTION disk,
      TYPE THE following sequence of commands:

	OLD <file name>
	COMPILE PUB:<104>

      The following programs must then be re-protected with
      a <232> protection code:
	
	PUB:LOGIN.BAC
	PUB:LOGOUT.BAC
	PUB:UMOUNT.BAC

   4) For each file in account [1,4] on this disk, type the
      following sequence of commands:

	OLD <file name>
	COMPILE LEADS:<104>

      The following program must be re-protected <232>:

	LEADS:WRITE4.BAC

   5) USE PIP TO COPY THE CONTENTS OF THE [1,5] ACCOUNT
      INTO LEADS0: WITH PROTECTION CODE 56.

	PIP LEADS0:*.*<56>=DEV:*.*[1,5]

   6) Create a file named DATAB.LTX in the PUB: account, with
      the following lines in it:

	PUB:BEGIN.BAC
	[account number],LEADS:OPTION.BAC
	[account number],LEADS:OPTION.BAC
	    .
	    .
	    .

      This file contains the list of LEADS accounts on your system.
      The first line contains the name of the program used to create
      a LEADS data base.  If you wish to control this function further,
      change the file name here.  LOGIN will chain to line 32000
      OF THE PROGRAM SPECIFIED (WHICH SHOULD BE "BEGIN").
      CONSULT THE "LEADS DATA BASE MANAGER'S MANUAL" FOR
      FURTHER INFORMATION ON THE "DATAB.LTX" FILE.

   7) USE PIP TO COPY  OPTION.LTX  FROM THE LEADS0: ACCOUNT
      INTO THE # ACCOUNT OF EACH LEADS DATA BASE ACCOUNT ON
      YOUR SYSTEM.  FOR EXAMPLE:

          PIP *.*[ ACCOUNT NUMBER , 0 ]<40>=LEADS0:OPTION.LTX

<end>
