When giving input to your program, you probably gave it something it was not designed to (e.g. maybe it needed a number and you typed in text). From HTTP://WWW.AdaIC.org/standards/95lrm/html/RM-A-13.html : "[..] The exception Data_Error can be propagated by the procedure Read (or by the Read attribute) if the element read cannot be interpreted as a value of the required subtype. This exception is also propagated by a procedure Get (defined in the package Text_IO) if the input character sequence fails to satisfy the required syntax, or if the value input does not belong to the range of the required subtype.

Run it again under the debugger, and set a break on exceptions. Then you will be shown the exact line that is causing the problem Or, if using GNAT, add an exception handler that dumps the stack symbolically; then you can see the exact line without the debugger. -- -- Stephe ^ permalink raw reply [flat|nested] 4+ messages in thread

Get a text book on Ada. Anybody using Ada knows what this means.
See RM A.13(13) You probably read a data item from a file or keyboard input that
does not have the expected type.
