Re: [Lazarus] Subroutine ?
Interesting and I didn't know you could do that. But, more of what I have in mind is. I have a bunch of database components on a form, I want them to be enabled only after hitting the edit or insert button on the DbNavigator. Since this is going to occur in multiple points in my button procedure, it would be programmatically better if this could be done in a sub procedure. Also, I have fields that are dependent on other fields, so fieldsz only would become active if fieldx has a 'Y' in it.

Debian testing also has libmysqlclient 16 and mysql-server 5.1.
mysql version is a disaster (and one of the reasons why I avoid mysql when I

should link to mysqlclient.so (using the symlink, the unix way).
Anyway, long story short, FPC has a provision for such mistakes, -XLA
Try passing -XLAlibmysqlclient.so.15=libsqlclient.so.16 and pray.

[Lazarus] Astronomy App
A few years ago, I wrote an app in Delphi to record my progress on observing the Messier List ( an astronomical observing challenge). The program has several very useful reports: * Rise and Set Report, which lists objects (all, seen, or unseen) and then sorts the output on how many hours the object will be up when the sun isn't. You may also select a specific constellation. * Standard Report, which lists if, when, and where an object was observed. This is useful for applying for observing certificates from the Astronomical League. I turned mine in and was awarded the Messier Certificate without any complaints from the AL. It also can export the data to csv, which can easily be imported to Calc or most other spreadsheets. * Statistics report, which was an excuse for me to play around with bar & pie charts. The data is kept in a MySQL Database, which allows me to keep multiple databases. I am currently working on my Herschel 400 list, which is a seperate database. I have made an attempt to convert it to Lazarus and it basically works, but could use some buffing and fluffing. There are Windows and Mac apps that do this already, but none for Linux.
