Novice question but... 1

I have been working on VB and I have been recently assigned to make some changes to a delphi module since they are "similar" according to my boss. I was doing just fine until I met this line of code:

settings := settings Or $20;

where settings is an integer. Can you please tell me what $20 stands for?

ps: settings is then saved in registry.

Thanx

The $ signals a hexadecimal number. So $20 is 32 decimal. It is also 00100000 in binary which is likely to be more relevant in your example.

The actual statement

settings := settings OR $20;

sets that bit to a one and leaves all the other bits in the variable 'settings' unchanged.
