Installation Procedures " The DISPLAY EDITING SYSTEM installation tape for CMS contains three (3) .
files in CMS 'TAPE LOAD' format. There are no tape labels and each file is
followed by one tape mark.
File 1 includes all material necessary for installation of the DISPLAY EDITING SYSTEM. Included are the ECOMMAND and EDGAR load modules, a set of
sample "DEFAULT" EXECS, a sample "EDGAR $PROFILE" and the EXECs and
TEXT files required to perform the installation procedure.
File 2 contains the assembly language source code and object form of the system modules and the macro libraries required to assemble these modules.
It is not necessary to load this file for installation or maintenance purposes.
File 3 contains the MACRO and COpy files which comprise the macro libraries
included in file 2.
Assembly of the DISPLAY EDITING SYSTEM modules requires the vs H-LEVEL ASSEMBLY LANGUAGE PROGRAM PRODUCT (5734-ASl) which in turn
requires the ASSEMBLER H/CMS INTERFACE IUP (5796-PEJ) for installation
under CMS. Assembly language modifications to the system are discouraged
as normal maintenance of the product may include substantial revisions in
source code. Prior to installation the user must assure that the Extended Full Screen 3270 Console Interface for VM/370 (PRPQ # 5799-AWP) or equivalent has been
included in the VM/370 system on which the DISPLAY EDITING SYSTEM is to
be installed. Furthermore, if remote 3270 systems are to be utilized by the DISPLAY EDITING SYSTEM, the vM/370 control program must include the fix
for APAR vM07289. In addition, the 3271 control units which will be utilized
must include the following EC's (Engineering Changes): 717956, 739540, and 739278.
The DISPLAY EDITING SYSTEM may be installed to run either always in the
CMS user program area, or in a Discontiguous Shared Segment (DCSS) if
available. The two methods of installation will be discussed separately.
Installing For Use In The User Program Area Only
Installation Procedures 52
1. Generate a vM/370 system which will support the DISPLAY EDITING SYSTEM environment. This includes installing the PRPQ 5799-AWP.
Access the disk on which the Display Editing System is to reside as your
'A' disk. Be sure the disk contains at least 280 CMS data blocks.
2. Attach the installation tape to your virtual machine as 181.
3. Enter the CMS command "TAPE LOAD". The DISPLAY EDITING SYSTEM is now installed and ready to be used. If the
disk on which it was installed was the CMS sysres (190), resave the CMS
system (SAVESYS CMS).

Installing Fo.,. Use In, Either A or The User Program Area
1. Generate a VM/370 system which will support the DISPLAY EDITING SYSTEM environment. This includes installing the PRPQ 5 799-A wP, and
generating an entry in the DMKSNT system name table as follows for the
EDGAR DCSS. LABEL NAMESYS SYSNAME = xxxxxxxx, (name af EDGAR DCSS) SYSPGCT = 16, SYSPGNM = (272-287), SYSHRSG = (17), SYSS/ZE = l024k, any value ;s valid VSYSRES = IGNORE, VSYSADR = IGNORE, SYSVOL = valid, SYSSTRT = (mm,nn)
The SYSVOL and SYSSTRT information pertain to the location of the cylinders
on which this DCSS is to be saved. These must be supplied by the system
programmer doing the installation. (See vM/370 Planning and System Generation Guide, Defining Your vM/370 System, GC20-180l). The SYSNAME parameter may be assigned by the system programmer. The same
name must be entered as part of the IUP installation procedure INSTED. The SYSPGNM and SYSHRSG load the shared segment at location x'110000'. These values may be changed to fit the installation's needs.
2. Logon to a virtual machine with "E" class privilege and a virtual machine
size at least X' 12000' bytes larger than the value represented by the SYSPGNM parameter above.
3. Access the disk on which the DISPLAY EDITING SYSTEM is to reside as
your' A' disk. Be sure the disk contains at least 280 eMS data blocks.
4. Attach the installation tape to your virtual machine as 181.
5. Enter the CMS command "TAPE LOAD". 6. Enter the command INSTED xxxxxx, where xxxxxx is the name of the
EDGAR DCSS assigned in step one (1) above. You will be prompted for
any additional information or errors encountered. NOTE: The use rid
from which you invoke INSTED will require 'E' privilege class for success­
ful operation.
The EDGAR component of the DISPLAY EDITING SYSTEM may be regenerat­
ed by using the INSTED exec. The INSTED exec when entered with one (1)
entry parameter will generate the version of EDGAR which is capable of
running in the DCSS. If EDGAR is generated in this manner and the DCSS cannot be loaded, EDGAR will be executed from the user program area (X'20000'). The INSTED exec when entered with no parameters will generate
the version of EDGAR which is capable of running only from the user program
area. This form should be used if the DCSS will never be loaded.
