I don't even know what this PascalSCADA is good for but their FAQ in

--------------
Can I use/install PascalSCADA 0.7.2 with Lazarus 1.0.2?
Yes, you can, but to use it, you have two ways:
Update some parts of PascalSCADA (ZeosLib)
Remove the database support of PascalSCADA (Database still not used on PascalSCADA 0.7.2)
The easiest way is update the ZeosLib. To do this download [this file]. When download finishes, close Lazarus, unpack and replace the folders pascalscada/zeoslib/src and pascalscada/zeoslib/packages by the uncompressed folders.
