It occurs on LOCATE command.Thank you in advance,Zbi RE: Internal error 5333 Elkari (Programmer) 26 Aug 02 10:18 From what I found out, it has to do with a NULL memory pointer or corrupted record indicator.Try packing the DBF you were trying to LOCATE into.This clean up should straighten up any record pointer problems. RE: Internal error 5333 circes9 (Programmer) 26 Aug 02 11:24 packing a corrupt database can be FATAL to your data. You may lose more than you expected.You may wish to browse your data and see what you can see before making any changes to it.Did this error occur in some new code or an existing program?This may give you a clue as to where to begin looking.Good luck RE: Internal error 5333 Elkari (Programmer) 26 Aug 02 11:35 Circes9 is right.If the DBF itself is corrupt, ie. it can't be openned due to header problems, then packing it would cause even more problems.Fix any structure problems first.However, if the DBF is intact and all that is wrong is a large amount of records marked as deleted, a packing would do it some good.

deal? (Excellent reply contributed by David Husnian.) Clipper and most computer languages use a binary floating point format for their real numbers. This causes precision errors which commonly show up in calculations, comparisons and when rounding. The problem is related to trying to represent an infinite number of decimal numbers into a fixed number (and a small fixed number at that) of binary bits. Statistically, there aren't any numbers that can be represented exactly, of course, from a practical standpoint some can be (but they are all somehow related to powers of 2, like 1/2 or http://www.tek-tips.com/viewthread.cfm?qid=344848 3/8 or 127/128 or ...). Taking .275 out to just 16 bits yields: 0100011000100111 but that is really only .274993896484375. It is impossible to represent .275 accurately in a binary numbering system, even with unlimited bits, let alone the 64 bits that Clipper uses (all of which aren't used for the decimal portion). Most modern languages use a format defined by the IEEE. An IEEE-compliant double precision implementation http://www.davep.org/clipper/FAQ/clipper-5.html meets the following criteria: 1 sign bit, 52 bits for the mantissa and 11 for the exponent. 2.22 * 10 ^ -16 is the smallest number that, subtracted from 1.0, gives something different than 1.0. Normalized to 1023, which means that 10 ^ 0 will be kept as 1023, with 10 ^ -1 as 1022 and 10 ^ 1 as 1024. Smallest useable floating value is 2.23 * 10 ^ -308. Largest useable floating value is 1.79 * 10 ^ 308. In the IEEE standard, rounding is considered to be finding the closest representable number to the "exact" number. Not an easy task, particularly at the level of Clipper. There are only two complete solutions: use only integers (for example, use 1234 to mean 12.34) or use a decimal numeric format like BCD. With Visual Objects you will be able to make variable declarations such as LOCAL i AS INT, which will have the effect of forcing only integer values into a variable. CA-Clipper 5.3a is compiled and linked with the 8.0 release of Microsoft C, including the standard math library component. The rounding problems under this library are likely to be somewhat less severe. 5.2 Why is "ABCDEF" = "ABC" turn

Answer: Such an internal error can be recognized by its title "Problem Occurred" and starts with "An internal error occurred during:
assertion causes the base of an internal error. It is all environmentally related and does not branch to Clipper internal Error block whenever it occurs. In this paper, a set of unexplained internal errors are investigated and their casual factors are carefully examined. 1. Introduction Every developer gets a runtime error when they are involved with their new development, but in fact, none of them can accept or tolerate any of these unwanted errors after the product has been released. Although most Clipper Errors branch to the current error block, some internal errors do not. In a very recent paper by Key, S (Ref. 4.), an incomplete subset of Internal Clipper Errors were documented. We hope, in this paper, to both augment Key's work by further examining other less widely understood internal errors, and re-examine those errors listed by Key in his original paper. Error characteristics will be analyses, with an emphasis on root causes. 2. What are Internal Errors In Clipper, runtime errors are dependent totally on the error handler and the subsystem that generates the error. Errors generally occur either because of mistakes in the program code (i.e., type mismatch, divided by zero) or because of some condition of the environment (i.e., out of file handles, file sharing violations, memory low). The error handler communicates with the subsystem by returning a value. This value indicates what the subsystem should attempt to do to recover from the error. The legal values are generally determined by the values handler. These type of errors, in fact, can be trapped in the error system so that the application which has been affected does not necessarily terminate. However, sometimes it is not possible to trap a runtime recoverable error due to an invalid value returning from the error handler to the subsystem (see Ref. 1). On the other hand, whenever a program code is executed in the error system, ErrorSysQ function, before invoking the ErrorBlockQ function, an error handler is unavailable to the ErrorSysQ and unrecoverable error is caused. This usually happens because such errors can not branch to the error block so that the ErrorSysQ is unable to execute the error block. These errors are, in general, reported w
