Re: [Harbour] Re: Przemyslaw, I need to know your position about HB_PP_MULTILINE support
Hi Angel, Hi Viktor What rule do I have to issue to make this work ? Procedure Main cString := 'ABC' ? cString[2] // -- 'B' Return Xbase++ users are VERY used to this syntax and makes string manipulation programs much simpler. It's already implemented in xhb lib via operator overloading, so you can either use that one, or similar implementation can be copied to hbxpp (with possible adjustments to fully mimic Xbase++ behavior). You can find current implementation in these files: contrib/xhb/xhb.ch contrib/xhb/xhbcomp.prg contrib/xhb/xhbmsgs.c (for array index support, you only need just a small part of the above code) Brgds, Viktor ___ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour

Angel, Can you tell, if Xbase++ support negative indexes in 'string[ n ]' operations? I'd also be interested in the error messages you get when using off limit or zero index.

Thanks, so the same extension exist as in xhb. I'll update SVN.

Viktor Szakáts wrote: Thanks, so the same extension exist as in xhb. I'll update SVN. IFAIR, xHarbour allows off-limit indices to return an empty string. That was the main drawback, that does not help to find buggy code by RTE. F.e. 'abc'[1, 2, 3, 4, 5, 6] does not RTE.
