"I ran a compiled Ada program and got back the error :
raised ADA.IO_EXCEPTIONS.DATA_ERROR
Does anyone know what this means?"
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.
