Switching languages???

Are you a Visual Basic pro wanting to write something in Visual Foxpro?

Are you a Java person needing to cut a few lines of VB code?

Or are you a new programmer who is wondering what's the difference between languages?

This page is a cross reference of some of the common commands.

I program in a couple of languages, and in my old age I sometimes get mucked up when I switch. The syntax is slightly different for different languages, and I sometimes forget the mundane finer points. This page is a cross reference of some of the common commands.

This is NOT a newbee page. It assumes you know the basic rules of the road.

Cross reference table for common commands
Cross reference table for common functions
Cross reference table for basic syntax
General all languages
Java
Visual Basic
Visual Foxpro
for example: Let's take the conditional IF command.
In Visual Basic, the IF command is IF condition
       THEN[statements]
   [ELSEIF condition-n
       THEN[elseifstatements] ...
   [ELSE[elsestatements]]
END IF

in Visual FoxPro (another Microsoft product no less ((but I think a bit better actually)) )

the Visual FoxPro IF command is IF (Expression)
    [THEN optional and not often used]
    ELSE
ENDIF
while in Java....
the Java IF command is if (z & xxx)
      System.out.println( "z&xxx if" );
   else
      System.out.println( "z&xxx else");
Slightly different, but enough to slow you down when you want to get a job done quickly. And on top of it, the way the conditions are stated is also slightly differen, as are a bunch of other things, like strict typing and adhering to upper-lower case, etc etc..
So... this is a listing of the basic commands and cross references them to other languages.
This section will also contain details for cross referencing other programming tasks, such as:

passing parameters
handling variables
calling methods (procedures, functions, etc.)
naming conventions, and as much more as possible.

This section does NOT get into correct Object Oriented programming techniques or other simple programming concepts. It's strictly a cross reference for common functions and commands.

Please contribute ideas. I'm sure I didn't cover some of the more basic things which I take for granted, but someone switching for the first time might not know.
Like setting up the computer's system variables and search paths for Java. Rather simple unless you're doing it for the first time. Especially JSP and server stuff.

General
SQL and data
Java
JDBC
