Hi everyone,

I'm very new to Host Access and D3. We're currently working in a D3 Pick environment using the TCL (Terminal Command Language) prompt, and I need to learn everything from scratch.

I do have access to Rocket Software's D3 reference manuals, but they're quite large and a bit overwhelming to read cover to cover.

Could anyone please suggest the best places to find learning materials - especially video tutorials that cover basic concepts, TCL commands, creating simple programs, and understanding how everything works with real examples?

I really prefer videos or more practical, hands-on resources rather than just manuals.

Thanks so much in advance for your help!

Is this D3 over Linux or Windows?

Hi Rima,

I agree that reading the Reference Manual will be overwhelming. It's designed as a reference rather than a how to guide. It's best treated as a reference book, not a novel. Think of what you want to do, then look up the likely commands in the index for the syntax.

As Brian asks, is this D3 on Linux or Windows? There are some slightly different techniques between the 2 versions.

Also, Jon's recomendation of JES & Associates' free PDF book is a good one. JES has been involved with Pick/D3 for probably about 40 years.

Best wishes,

Warwick

Rima,

JES and associates have a free PDF book on a basic introduction to Pick. You can google it and download it. Excellent introduction to the basics.

Rima, check out some of these videos.    Please remember that D3 is a flavor of the Pick (MultiValue) database.  All the Pick databases are about 95% plus compatible BUT they all know how to CREATE, READ, UPDATE and WRITE the database.

Here's a couple of documents I put together. The health check document is a guide for people supporting a D3 Windows system to make sure there is no trouble lurking, but it's also informational about some common D3 Windows commands. The other two are zip files that you unzip and double click the html document to navitate the tutorial.

Hi Brian,

thank you sharing these documents with me.

Regards,

Rima

I have some more documents on some more advanced topics when you're ready, specifically the D3 MVS REST services tookit, MVSP, and FSI Hot Backup.

Hy @Brian.. 
I am interested in this MVSP and HotBackup documentation
