IBM Pascal Compiler Aug81 pdf (via: Bitsavers’ Index of /pdf/ibm/pc/dos)

Posted by jpluimers on 2013/05/26

Wow, I didn’t know that IBM had their own DOS based Pascal compiler for the PC in 1981, but they did, and BitSavers just uploaded their manual

document moved from

It is part of their “Personal Computer Computer Language Series”

From the era of DOS Pascal compilers before Turbo Pascal.

Delphi XE2: spontaneous Product or License Validation Error | General

Posted by jpluimers on 2013/05/24

Every once in a while an AV in Delphi manifests itself in a very odd way.

Usually it is refactoring, code completion or any of the ‘insight’ features doing odd things.

This time, it got me into a Product or License Validation Error | General:

Product or License Validation Error

Your Embarcadero product or license can’t be validated.

If you see this page when you’re using a valid license and official version of the software, please submit an installation support case for further assistance.

If you need a trial license and official trial software download, visit our Trial Downloads page.

To purchase a product license and receive a certified download, please see our How to Buy page.

Too bad the error hard-quits Delphi, thereby loosing all your work since the last save. Even more reason to safe often.

None of the reasons mentioned in Starting Delphi or C++ Builder results in Product or License Validation Error applied.

Restarting Delphi XE2 solved the problem.

Great as it has steps both for Windows Vista SP1 and SP2, and steps for Vista RTM.

Posted by jpluimers on 2013/05/23

Interesting: this USD 300 device might be a lot cheaper and versatile for my Nikon D700 and D300 than the USD 700 Nikon WT-4/4A transmitter.

On my research list: Distinguishing USB devices

Posted by jpluimers on 2013/05/23

So I won’t forget:

delphi – How to distinguish flash drives? – Stack Overflow.

In that answer, Dan C talks about VID / PID (Vendor ID and Product ID) and how to get some of the serials without WMI.
