Activates conditional compilation support within comments in a script.
The @cc_on statement can turn on conditional compilation within comments in a script.
It is not common to use conditional compilation variables in scripts written for ASP or ASP.NET pages or command-line programs. This is because the capabilities of the compilers can be determined by using other methods.
When you write a script for a Web page, always put conditional compilation code in comments. This enables hosts that do not support conditional compilation to ignore this code.
An @if or @set statement outside of a comment also activates conditional compilation.
The following example illustrates the use of the @cc_on statement.
/*@cc_on @*/ /*@ document.write("JScript version: " + @_jscript_version + "."); document.write("<br />"); @if (@_win32) document.write("Running on the 32-bit version of Windows."); @elif (@_win16) document.write("Running on the 16-bit version of Windows."); @else document.write("Running on a different operating system."); @end @*/
