9.7 Repetitive Compilation (Compile-Time Loops)

HLA's #while..#endwhile and #for..#endfor statements provide compile-time loop constructs. The #while statement tells HLA to process the same sequence of statements repetitively during compilation. This is very handy for constructing data tables as well as providing a traditional looping structure for compile-time programs. Although you will not employ the #while statement anywhere near as often as the #if statement, this compile-time control structure is very important when you write advanced HLA programs.

The #while statement uses the following syntax:

#while( constant_boolean_expression )
     << text >>
#endwhile

When HLA encounters the #while statement during compilation, it will evaluate the constant ...
