[fpc-devel] How to convert set to integer and vice versa

[Gennady Agranov]

Hi,

I am new to FPC, but I do like it - thanks!

We are trying to switch from Delphi to FPC, but I am stuck with the 
following issue - in Delphi you can cast "set" to "integer" and get it 
back later - again by casting. In our case it is used for persistence 
purposes.

We have a lot of different set types - i really do not want to write 
set<->integer converter for every set type we have :(

Actually I did find a way - I use ^ and @ and cast pointers,
but is there a way to write general set<->integer converter in FPC that 
I do not have to worry whether it will work or not?

And what actually -CPPACKSET=0 does - documentation is not clear - at 
least for me :)

Thanks,
Gennady
