So, in pascal, you don't test if a variable contains an uninitiliazed
value, you initialize it before referring the variable.
And before assigning a value, you verify it is in the range.

In short:
Different codepage strings and raw strings should be considered
different incompatible types. Pascal is a hardtyped
I know it is a dangerous question that can easily turn into a holly
war, flame or whatever. But here it is.
I have only used Lazarus or a general editor (usually Jedit, geany).
Time ago I checked a little MSEgui and, well, I didn't go for it.
In MSEgui I found fonts small and interface not very

prepare again the query.
It is not that different from saving the original sql string and
