If you do not already have an account on a VMS cluster that runs SLD offline software, your first step is to get one. If you are not at SLAC, ask your fellow group members for the name of the VMS cluster that you should use. If you are at SLAC, you can get an account on the SLACVX VMS cluster as follows.

- Get a new user form from the service desk in the lobby of the SLAC computer center.
- Fill it out and have it signed by one of Richard Dubois, Terry Schalk, or Karen Heidenreich.
- Return it to the SCS Service Desk.
- They typically take one or two days to create the account.

- If this window is already logged on to your offline software VMS host, you are all set.
- If this window is logged on to a different VMS host,
type
`SET HOST`followed by the name of the host you want to use. You will then be prompted to log on. - If this window is logged on to a non-VMS host,
type
`telnet`followed by the name of the host you want to use. You will then be prompted to log on.

The VMS operating system is NOT case sensitive. In the following examples, VMS commands are written in upper case, but you can actually type them any way you like.

The next few steps will help you confirm that you are logged on to an appropriate VMS host and that your account has been correctly configured.

If the result is something like

"DUCSROOT" = "$255$DUA0:[DUCS.]"

you are on a VMS host that is suitable for running SLD Offline software.

If the result is something like

%SHOW-S-NOTRAN, no translation for logical name DUCSROOT

the VMS cluster you are logged on to does not contain the SLD offline software. Ask your collaborators for the name of the appropriate VMS cluster.

The result should be something like

AFBCH :PROD HEAVY :PROD MCHRWG57:PROD ONLCRID :PROD TAU :PROD CART :PROD IDA :PROD MCHWK :PROD ONLDC :PROD TRACK :PROD CATSRV :PROD IDA3 :PROD MCKORZ :PROD ONLERR :PROD TRIGGER :PROD CERNV :PROD JAZELLE :PROD MCL63 :PROD ONLLAC :PROD UDUC :PROD CETI :PROD JAZQAPT :PROD MCL72 :PROD ONLVTX :PROD UEDT :PROD CRDRAWD :PROD KAL :PROD MCL73 :PROD ONLWIC :PROD UEVE :PROD CRID :PROD KON :PROD MCL74 :PROD PAW :PROD UGRA :PROD DATACAT :PROD LAC :PROD MCLEPT :PROD QCD :PROD UHIS :PROD DC :PROD LUM :PROD MCLUND :PROD QPOL :PROD UMOR :PROD DISPLAY :PROD MC :PROD MCMUBG :PROD RECON :PROD UTIL :PROD DOC :PROD MC1TRK :PROD MCRADC :PROD RECVRT :PROD UTPU :PROD DST :PROD MCBEAM :PROD MCSUSY :PROD REXX :PROD UVAXSRV :PROD DSTUTIL :PROD MCBHAG :PROD MCTWOG :PROD RTH :PROD UWRI :PROD DTAG :PROD MCBHLM :PROD MCUCLA :PROD RTOFF :PROD VMUTIL :PROD DUCSNEWS:PROD MCBREM :PROD MCYFS :PROD SDISPLAY:PROD VTX :PROD ELECWEAK:PROD MCBZ :PROD MFIT :PROD SGNL :PROD VXFNDTMP:PROD EMI :PROD MCCOS :PROD MIDAS :PROD SLD :PROD VXFNDUTL:PROD ERRLOG :PROD MCDIAG :PROD MORTRAN2:PROD SLDMIDAS:PROD WIC :PROD EXAMPLES:PROD MCEEG :PROD NAMES :PROD SMON :PROD WMATCH :PROD FASTMC :PROD MCEP :PROD NAPL :PROD STATUS :PROD WUTIL :PROD GEANTSLD:PROD MCHRWG54:PROD NETIDA :PROD SWIM :PROD ZXFIND :PROD

If you got the above result, it means that your account is correctly configured to use SLD offline software. We'll get back to the details of DUCS later.

If you did not get anything like the above result, it means that your account is not correctly configured to use SLD offline software. Ask your system manager to configure your account for SLD offline software use. They will at least need to make some changes to your LOGIN.COM file. If they don't already have one handy, they can start with the example in SLACVX::$255$DUA0:[DUCS.UTIL]LOGIN.COM.

Type `SHOW QUOTA`

You will either get a response that quotas are not in effect on your disk or you will get a response that you have a certain number of blocks used, available and authorized. A block in VMS is 512 Bytes. For your initial work, 10,000 blocks is a reasonable amount of space. Later, when you get to the section of the workbook on Writing Code, you may want more like 30,000 blocks.

For now, if you have less than 5,000 blocks authorized, check with your system manager.

A detailed tutorial on the VMS operating system will come later in this workbook. For now, just keep typing the commands we tell you. We are rushing past the detailed description so that you can get your hands on some real data before the day is done.

You should run your SLD offline software jobs from subdirectories of your login directory. Create your first subdirectory.

Type `CREATE/DIRECTORY [.subdirectory_name]` including the
brackets. For example, `CREATE/DIRECTORY [.FIRST]`.

While you are at it, also create a directory on the scratch disk where the SLD offline software can store any temporary files it needs to make.

Type `CREATE/DIRECTORY $SCR:[your_account_name]` including the
brackets. For example, `CREATE/DIRECTORY $SCR:[FRED]`.

One VMS hint we will tell you now. VMS is very friendly about accepting
abbreviations for commands. In the above examples, you could have typed
`CRE/DIR` instead of `CREATE/DIRECTORY`.
If you have supplied too few characters for VMS to tell what
the command should be, VMS will ask you to supply more characters.
And remember, as we mentioned before, case does not matter in VMS commands.

To see what files are in the current directory, type `DIRECTORY`
or just `DIR`.
