MVtools Files & Accounts

MVtools consists of a number of basic programs (On file MVBP) and a number of parameters or properties on MVOB. This section describes how you can create the accounts and files ready for transferring the downloaded basic programs into. The parameters or objects will later be automatically unpacked when you run a SETSYS from TCL.

The MVT account

If you are setting up the system yourself using downloaded sourcecode will need to create this account yourself and create the files MVOB and the program file MVBP.ver for the relevant release of the programs. It is possible to set up the MVtools files directly onto your application account. The method described here is only a recommendation but has the advantage of allowing the system to be reset to a previous version of the software tools

The SYSTEM file should not be created but should be a pointer to the SYSTEM file on SYSPROG or the file that holds entries per logon account. Eg on D3 :

001 Q
002 SYSTEM.
003

Apart from the workfile MVWORK these files should all be created in the MVT account. The workfile must be created separately in each logon account as Mvtools will need to create sub-files for each user at run-time. There are around 350 programs so a good file size is 23,1 for the dictionary and 353 for the data section The MVOB file will be smaller, and a sensible size to start this file would be 1,3 for the dictionary and 1,101 for the data. This file can be created in each account if each account is to have it's own settings, users etc., The MVT account should have the program file named with a version number suffix Eg MVBP.43 for version 43 and the parameter file MVOB created within it. This allows new versions of the programs to be loaded at the same time and for applications to be easily switched from one version to another and back again simply by changing the pointer to the programs should any problems occur. The version number to use should be in the subject line of the email containing these attached programs.
