My point is that the loss of a tab character - an *invisible* character - changes how the program operates, where as in VFP, if the programmer gets the code in the right spot with the right placement of the ENDIF, the loss of a tab at line 4 (line 4 should be in the loop) will not cause a problem. In Python it will cause a problem, in VFP it won't. I don't like the idea of the loss or addition of invisible characters making code run differently. But let me emphasize that I do like many of the other things I saw in Python. I guess it's a matter of what someone can live with after evaluating the entire language.

You've told the compiler that the loop structure has ended by outdenting, just as if you were to write in VFP: DO LOOP CONSTRUCT Code Line 1 && Supposed to be in the loop Code Line 2 && Supposed to be in the loop Code Line 3 && Supposed to be in the loop ENDDO Code Line 4 && ALSO supposed to be in the loop!!!!!!!! Code Line 5 && Not supposed to be in the loop. Code Line 6 && Not supposed to be in the loop. The 'ENDDO' is the closure of the block. Looking at the code there is no way for you to determine, unless you know what Line 4 is supposed to be doing, that there is an error here. The same is true in Python: if you are sloppy and place a statement outside of the loop structure, it won't get looped. -- Ed Leafe -- http://leafe.com -- http://dabodev.com [excessive quoting removed by server] _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
