Migrating from VM/CMS (PSUVM) to Other Systems

As announced in the Fall of 1998, the Center for Academic Computing will be terminating the PSUVM (VM/CMS) system on June 30, 2000. Because of year 2000 compliance problems, we recommend that most people attempt to be off the system before December 31, 1999. This will ensure that they are not trying to use programs that may no longer function correctly due to date dependencies.

To assist you in moving your files and applications from VM/CMS to another system, the CAC has published instructions on the Web at http://cac.psu.edu/vmcms/general.html below are two examples.

If you need assistance, please contact the CAC Help Desk by stopping by 215 Computer Building, e-mailing helpdesk@psu.edu, or by calling (814) 863-2494. If you have questions about your VM/CMS account, contact the Computer Accounts Office at accounts@psu.edu or (814) 865-4772.

Moving files from PSUVM to your Windows or Macintosh computer

With the announcement of the discontinuation of VM/CMS, many people are asking how to move files from the PSUVM system to a Windows or Macintosh computer. This article will explain how to do this using File Transfer Protocol (FTP) software. The FTP software programs Fetch for Macintosh and WS_FTP for Windows are available on the CAC's Internet software CD, which can be obtained from the CAC Help Desk in 215 Computer Building or 2 Willard Building.

Note that some files must be converted before retrieving them with FTP. In general, raw data files and files that a person can read and understand on VM/CMS using XEDIT can be copied without any conversion.

Download Procedure

1. Logon to your VM/CMS account, issue the command DISKLIST, and make note of your disk addresses (100, 101, 102, etc). You will need this information in step 4. Note that you need only disk addresses that are associated with your user ID. They will normally be listed as R/W (read/write). The R/O (read/only) disks labeled HELP, N-DISK etc. contain public files, not your private files. Convert files if needed; see "File Conversion notes" below for instructions.

2. Use an FTP program such as Fetch for Macintosh or WS_FTP for Windows. Double-click the application.

3. Fetch users will be presented with a "New Connection" window. If this window does not appear, select "New Connection" from the "File" menu. WS_FTP users will be presented with a "Session profile" window. If this window does not appear, click or select the "Connect" button.

4. In the dialogue box that appears, enter

Note that in the above example in the "directory" field, "xyz123.100" is analogous to your PSUVM user ID followed by a period, then your disk number. This gives the user xyz123 access to the minidisk having an address of 100.

Click OK, and you should now be able to start downloading your files to your local computer.

FTP Client Usage

WS_FTP should display all of the files on the selected minidisk in the right hand column under "Remote System". You can then select which files to download (on the right), choose the local directory (on the left), choose ASCII or Binary at the bottom and then select the "<-" symbol between the two to begin the download. Probably most files will be ASCII with the notable exception of SAS transport files which are binary.

Fetch should display a list of all your files on the selected minidisk. You can select one and then click on "Get File...". You can select several by command-clicking each file, or you can select a range of files by selecting the first file in the range then shift-click the last file in the range. Finally click on "Get File...".

If you have multiple disks on VM/CMS, use the "change directory" function in the FTP program to switch to another disk. For example, when you are finished getting the files from your 100 disk, then "change directory" to xyz123.101 to access the next disk.

File Conversion notes

  • Modules created from Fortran or some other compiled language cannot be copied. However, the source programs can be copied, and be made to run again on the desktop machine with just a little editing.

  • NOTEBOOK files should be converted with the MAILBOX command. They can then be downloaded and used as Eudora mailboxes. On PSUVM, type HELP MAILBOX for details.

  • NAMES files can be converted with the EUDORA command and then downloaded and merged with Eudora nickname files. On PSUVM, type HELP EUDORA for details.

  • EXEC and XEDIT macros. These files will not be directly useful on most desktop machines. However, they should probably be downloaded as text files since many contain techniques and ideas that could be converted to other situations. There are commercial versions of REXX and XEDIT available for some platforms for people who would like to continue using these tools.

  • SCRIPT source documents (formatted with Waterloo SCRIPT) should be downloaded as text files and then edited with your favorite word processor.

    For some files it may be more useful to format them first on VM/CMS and then download the MEMO or PRINT results.

  • SAS and SPSS program files should be downloaded as text files. With slight modification they will run on the Macintosh and Windows versions of these programs.

  • SPSS and SAS system files will have to be converted to a movable format before copying. There are now two new commands (exec files) on the system: PORTSAS and PORTSPSS. If you simply type a question mark after the command you will see a brief description of their use, e.g. PORTSPSS ? They work easily from within the FILELIST screen:

  • Next to the SAS system files, type PORTSAS (on PSUVM). This will create a file with the same name and a filetype of XPO on your E disk. Move this file to one of your permanent minidisks and then download it in binary mode.

  • Next to the SPSS file names, type PORTSPSS (on PSUVM). This will create a file with the same name and a filetype of POR on your E disk. Move this file to one of your permanent minidisks and then download it in TEXT mode.
