Step 1. Prepare to install service

Carry out preliminary steps prior to receiving service.

Electronic Service (envelope file)

If you have received the service electronically or on CD-ROM, follow the appropriate instructions to retrieve and decompress the envelope files to your A-disk. The decompression is currently done by using the DETERSE MODULE (shipped with VMSES/E).

The documentation envelope and the service envelope files must have a file type of SERVLINK. Make note of the file names that you are using as you will need to enter them in place of the variable envfilename in the VMFREC commands that follow.

Create a backup copy of the current High Level Assembler before applying the service tape. Save this copy of High Level Assembler until you have completed installing the service and you are confident that the service runs correctly.
Log on to the High Level Assembler service user ID: P696234J.
Establish read-write (R/W) access to the software inventory disk.
Command Explanation
link MAINT 51d 51d mr access 51d d
Commands to access the software inventory disk.
If you are applying service from tape, attach the tape to the user ID P696234J at virtual address 181. If you have received the service as an Envelope file, ensure the SERVLINK file is available on the A-disk.

Establish the correct minidisk access order.

The VMFSETUP command accesses all the required disks or SFS directories to establish the needed file modes.

Command	Explanation
`vmfsetup P696234J {HLASM\|HLASMSFS}`
	P696234J is the PPF that is shipped with High Level Assembler. If you have your own PPF override, substitute your PPF name for P696234J. Use `HLASM` if High Level Assembler is installed on minidisk. Use `HLASMSFS` if High Level Assembler is installed in SFS.

Receive Documentation. VMFREC with the INFO option loads the documentation and displays a list of all the products on the tape.

If receiving the service from tape:
Command Explanation
