Is it possible to use a reserved word as an identifier ?
For example – I want to name my variable or class “BEGIN” because, ummm, well I dont know just because.
Yes you can. Simply prefix the the name with an ampersand “&” escape character like this
var &begin : integer; // begin is a reserved word begin &begin := 123; end;

Change a Delphi field value without the change events firing (OnChange)

Ill show you how to do it with just one line of code using my custom unit for VCL and Firemonkey

This simple technique will show you how to write a SELECT statement that dynamically creates a number of rows. It can be used to duplicate data or create a numbers on the fly, so the data looks like this.
DATA 1 2 3 4 5

Drop by soon while I get stuck into creating more Delphi and Oracle posts
