Is Native Code Irrelevant?
by Wes Peterson

With Microsoft heavily evangelizing .NET, and Sun continuing to improve Java, many a developer and customer are torn between targeting native machine code or a just-in-time compiler.

Code Snippet of the Month

Languages Focus: End of Statement

In coding languages, common End of statement specifiers include a semicolon and return (others exist too). Also of concern when studying a language is can you put two statements on a single code line and can you break a single statement into two or more code lines.

ASP Classic End of Statement

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Response.Write("Hello1")

Response.Write("Hello2")
Response.Write("Hello3")

'The following commented code on a single line does not work...
' Response.Write("Hello4") Response.Write("Hello5")

'Two or more lines works too with a space+underscore:
Response.Write _
("Hello6")

FAQ of the Month: VBScript
Question: What does VBScript stand for?

Answer: VBScript is short for Visual Basic Scripting. VBScript brings scripting to a wide variety of environments, including Web client scripting in Microsoft Internet Explorer and Web server scripting in Microsoft Internet Information Service. It is used in Visual Basic, Access, Word, Excel, ASP, etc.
Language Basics Topic:
Tip of the Month

Short-circuit evaluation is a feature of most languages where once an evaluation evaluates to False, the compiler evaluates the whole expression to False, exits and moves on to the next code execution line. The ASP Classic if statement does not support short-circuit evaluation but you can mimic it. Use either an if..else if..else if statement or nested if statements. ASP code that makes use of this technique is frequenlty clearer and easier to maintain than the short-circuit equivalent.
