[DUG] Budget/Turbo editions of Delphi

[Gary T. Benner]

[Reply]

HI all,

As a Delphi teacher for some many years I found the Turbos irrelevant, as components are a fundamental part of good OO programming, and it was impossible to teach Delphi properly without new components being able to be created and installed in the IDE.

Personally I'd like to see a $25 fee for Academic Delphi - get's the Students into the system - and that the compiler be limited to what they could do ... eg. a nag screen at the start of any application not started within Delphi, and something like a 30 min time limit for application execution. .. etc

Otherwise the Delphi should run as per the real thing.

Students will get cracked versions otherwise, and they can be very creative at that.

HTH

Gary
