Quoted from the article. "Note a very important difference here—you did not need to recompile the procedure;" There are two examples in the article one in which you do have to recompile and one in which you don't. Assuming the example works as stated and thinking about this some more I am inclined to think that the "$if $else" code only executes when the package is loaded into memory for a given session. If the flag is changed in the other package then the other package is invalidated and must be revalidated again. I might have to create a couple test cases. - Ethan On 5/15/07, Brady, Mark <Mark.Brady@xxxxxxxxxxxxxxxxx> wrote:
Conditional compilation eliminates sections from the compiled code entirely. If you flipped the debug_flag to TRUE, you 'd still be printing Debug=F until you recompiled your source code.
